Cover letter [RESEND PATCH v3 0/3] sh: make early_platform code SuperH-specific
I recently started a discussion about the need for a proper early device probing mechanism[1]. One that would be based on real platform drivers and support both platform data and device tree.
While we're far from reaching any consensus on the implementation, Arnd suggested that I start off by moving the SuperH-specific early platform drivers implementation to arch/sh[2].
This series is the first attempt at making way for a new, less hacky implementation.
The first patch removes the last instance of a non-sh driver using the early_platform API. It can be removed since ARM no longer probes early drivers.
The second patch moves all the early_platform code to arch/sh.
The last patch prefixes all early_platform symbols with 'sh_'.

v1 -> v2:
- certain drivers are compiled for arm/mach-shmobile too - we need to add ifdefs for CONFIG_SUPERH around early_platform calls
v2 -> v3:
- added a stub for is_early_platform_device() which always returns false on non-SuperH architectures
RESEND: rebased on top of v4.18-rc1 and verified that there are no build failures.
RESEND AGAIN: rebased on top of v4.19-rc1 and verified builds again.
