scsi: ufs: exynos: Add support for Flash Memory Protector (FMP)

Add support for Flash Memory Protector (FMP), which is the inline
encryption hardware on Exynos and Exynos-based SoCs.

Specifically, add support for the "traditional FMP mode" that works on many
Exynos-based SoCs including gs101. This is the mode that uses "software
keys" and is compatible with the upstream kernel's existing inline
encryption framework in the block and filesystem layers. I plan to add
support for the wrapped key support on gs101 at a later time.

Tested on gs101 (specifically Pixel 6) by running the 'encrypt' group of
xfstests on a filesystem mounted with the 'inlinecrypt' mount option.

scsi: ufs: host: Rename structure ufs_dev_params to ufs_host_params

Structure ufs_dev_params is actually used in UFS host drivers to declare
host specific power mode parameters, like ufs_<vendor>_params or host_cap,
which makes the code not very straightforward to read. Rename the structure
ufs_dev_params to ufs_host_params and unify the declarations in all drivers
to host_params.

In addition, rename the two functions ufshcd_init_pwr_dev_param() and
ufshcd_get_pwr_dev_param() which work based on the ufs_host_params to
ufshcd_init_host_params() and ufshcd_negotiate_pwr_params() respectively to
avoid confusions.

This change does not change any functionalities or logic.

scsi: ufs: Convert all platform drivers to return void

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart from
emitting a warning) and this typically results in resource leaks. To
improve here there is a quest to make the remove callback return void. In
the first step of this quest all drivers are converted to .remove_new()
which already returns void. Eventually after all drivers are converted,
.remove_new() is renamed to .remove().

All platform drivers below drivers/ufs/ unconditionally return zero in
their remove callback and so can be converted trivially to the variant
returning void.
