Subject: [PATCH] kernel-modules: Fix storage module selection for

 sdhci/mmc/ahci

Currently the block driver detection for generic initrd doesn't include

the SD/MMC drivers so we fail to boot generic images on any device using

those platforms as boot devices when using a generic initrd. Add logic

to detect those modules. This primarily fixes embedded ARM devices but

also likely intel tablets/dev boards and enterprise hypervisors that

have the ability to boot from SD.

Also the ahci_init_controller misses a number of drivers that use the

libahci_platform module for the init so this fixes some missing achi

moduless too.

Finally it cleans up the ARM storage module hacks that the above now

deals with in a more generic manner.
