The driver started using the regulator subsystem and fails to build without
a dependeny on CONFIG_REGULATOR:

ERROR: modpost: "devm_regulator_register" [drivers/mmc/host/renesas_sdhi_core.ko] undefined!

The 'select RESET_CONTROLLER' needs to either go away or get changed to a dependency
in order to avoid Kconfig dependency loops here. It also turns out the the superh
version needs neither RESET_CONTROLLER nor REGULATOR, and this works because
CONFIG_OF is not set there.

Change both to a 'depends on', but add '|| !OF' for the superh case.

controller instance does not have Command Queue Engine HW support.

It was chosen to enable HSQ only for eMMC and SD/MicroSD cards
and not for SDIO as performance improvements are seen only for
the former.

Performance was measured with a SanDisk Extreme Ultra A2 MicroSD
card in a MediaTek MT8195T Acer Chromebook Spin 513 (CP513-2H),
