dc41b8bf3d mmc: omap3: fix block read function
The OMAP3 block read function is not following API and always returning
1 instead of read block count, fix it. Also to simplify code, merge it
with with a helper function, which was only called from the block read
function.

After this patch ext2 filesystem can be used properly.

89716964d9 mmc: add function prototype for mmc_set_dev in mmc.h
this eliminates compiler warnings when cmd_mmc.c is built with CONFIG_SYS_MMC_SET_DEV

the mmc_set_dev implementation in omap3_mmc.c is also tweaked to match
the new prototype in parameter naming and type

fccc0fcaaa OMAP3 Move twl4030 mmc function
Because twl4030 now has its own device files, move and rename
twl4030_mmc_config.

twl4030_mmc_config initializes the twl4030 power setting to
the mmc device.  Because it is in the twl4030 power domain, move
it out of drivers/mmc/omap3_mmc.c and into drivers/power/twl4030.c.

The function was renamed to twl4030_power_mmc_init because all
the functions in this file are to have the format

twl4030_power_<device>_<action>

In this case the suffix is mmc_init so
device : mmc
action : init
