[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.

clocksource: timer-ti-dm: remove the early platform driver
registration
platform: move the early platform device support to arch/sh
sh: add the sh_ prefix to early platform symbols
