Remove the sh7372 implementation and the shared ZBOOT MMC
and SDHI support code from the compressed ARM boot loader.
With this in place it is no longer possible to boot any
self-contained kernel for sh7372 directly from Mask ROM
via SDHI and MMCIF hardware.

This corrects a logic-error that I made in the original implementation.
An alternate patch would be to just remove these lines and
leave the clock running as it is reconfigured later on during
boot anyway.

This allows a ROM-able zImage to be written to eSD and for SuperH Mobile
ARM to boot directly from the SDHI hardware block.
This is achieved by the MaskROM loading the first portion of the image into
MERAM and then jumping to it. This portion contains loader code which
copies the entire image to SDRAM and jumps to it. From there the zImage
boot code proceeds as normal, uncompressing the image into its final
location and then jumping to it.
