fbdev/radeon: Initialize fb_ops to fbdev I/O-memory helpers
Initialize the instance of struct fb_ops with fbdev initializer macros for framebuffers in I/O address space. Set the read/write, draw and mmap callbacks to the correct implementation and avoid implicit defaults. Also select the necessary I/O helpers in Kconfig.
Fbdev drivers sometimes rely on the callbacks being NULL for a default implementation to be invoked; hence requiring the I/O helpers to be built in any case. Setting all callbacks in all drivers explicitly will allow to make the I/O helpers optional. This benefits systems that do not use these functions.
No functional changes.

fbdev: Remove FBINFO_DEFAULT from framebuffer_alloc()'ed structs
The flag FBINFO_DEFAULT is 0 and has no effect, as struct fbinfo.flags has been allocated to zero by framebuffer_alloc(). So do not set it.
Flags should signal differences from the default values. After cleaning up all occurrences of FBINFO_DEFAULT, the token will be removed.

fbdev: Add support for the nomodeset kernel parameter
Support the kernel's nomodeset parameter for all PCI-based fbdev drivers that use aperture helpers to remove other, hardware-agnostic graphics drivers.
The parameter is a simple way of using the firmware-provided scanout buffer if the hardware's native driver is broken. The same effect could be achieved with per-driver options, but the importance of the graphics output for many users makes a single, unified approach worthwhile.
With nomodeset specified, the fbdev driver module will not load. This unifies behavior with similar DRM drivers. In DRM helpers, modules first check the nomodeset parameter before registering the PCI driver. As fbdev has no such module helpers, we have to modify each driver individually.
The name 'nomodeset' is slightly misleading, but has been chosen for historical reasons. Several drivers implemented it before it became a general option for DRM. So keeping the existing name was preferred over introducing a new one.

fbdev: radeonfb: use generic power management
Drivers using legacy PCI power management .suspend()/.resume() callbacks have to manage PCI states and device's PM states themselves. They also need to take care of standard configuration registers.
Switch to generic power management framework using a "struct dev_pm_ops" variable to take the unnecessary load from the driver. This also avoids the need for the driver to directly call most of the PCI helper functions and device power state control functions, as through the generic framework PCI Core takes care of the necessary operations, and drivers are required to do only device-specific jobs.

video: constify fb ops across all drivers
Now that the fbops member of struct fb_info is const, we can start making the ops const as well.
This does not cover all drivers; some actually modify the fbops struct, for example to adjust for different configurations, and others do more involved things that I'd rather not touch in practically obsolete drivers. Mostly this is the low hanging fruit where we can add "const" and be done with it.

v2: - fix typo (Christophe de Dinechin) - use "static const" instead of "const static" in mx3fb.c - also constify smscufx.c

fbdev: radeon: use ktime_get() for HZ calibration
do_gettimeofday() is deprecated and a bit clumsy. This changes radeon_probe_pll_params() over to using ktime_get() with monotonic times. There is no need to check for negative values any more since the monotonic clocksource cannot go backwards, but I'm adding a check for zero-division in case of a bad clocksource.

video: fbdev: Convert timers to use timer_setup()
In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly. One tracking pointer was added.
