Add support for the AC5/AC5X SoC from Marvell. The NFC on this SoC only

Marvell's SDK includes some predefined values for the ndtr registers.
These haven't been incorporated as the existing code seems to get good
values based on measurements taken with an oscilloscope.

mtd: rawnand: Drop obsolete dependencies on COMPILE_TEST

Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it
is possible to test-build any driver which depends on OF on any
architecture by explicitly selecting OF. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.

It is actually better to always build such drivers with OF enabled,
so that the test builds are closer to how each driver will actually be
built on its intended target. Building them without OF may not test
much as the compiler will optimize out potentially large parts of the
code. In the worst case, this could even pop false positive warnings.
Dropping COMPILE_TEST here improves the quality of our testing and
avoids wasting time on non-existent issues.

mtd: rawnand: omap2: Actually prevent invalid configuration and build error

The root of the problem is that we are selecting symbols that have

The cleanest solution is to avoid using select.

This driver uses interfaces from the OMAP_GPMC driver so we have to
depend on it instead.

The Ericsson U300 platform was one of two ARM929 based SoC platforms for
mobile phones in ST-Ericsson after the merger of Ericsson with ST-NXP
into ST-Ericsson, the other one being the ST Nomadik.

The platform was not widely adopted in Linux based systems and was
replaced with the far superior ST-Ericsson U8500 in 2011, but Linus
Walleij kept maintaining the code for the whole time.

Linus continues to use the Nomadik machine, but decided to drop
u300 from the kernel as part of this year's spring cleaning.
Thanks for having maintained it all these years.

ECC: 16/40/60/70 bits/1KB.
CLOCK: ahb and nfc.
- RK3308 and RV1108(NFCv800).

CLOCK: ahb.

Supported features:
- Read full page data by DMA.
- Support HW ECC(one step is 1KB).
- Support 2 - 32K page size.
- Support 8 CS(depend on SoCs)

Limitations:
- No support for the ecc step size is 512.
- Untested on some SoCs.
- No support for subpages.
- No support for the builtin randomizer.
- The original bad block mask is not supported. It is recommended to use
