ENGR00127368 UBOOT: Make the android recovery code common for platformsrel_imx_2.6.31_10.09.00

Move the android recovery codes into common/recovery.c.
Cut the keypad detecting time. Now we only need detect
there's POWER and HOME key pressing at the time scanning
keyboard matrix. So user must hold these two keys when bootup to
enter recovery mode. This can reduce the uboot boot time with
recovery mode configured.

Later /cache file checking for recovery command should be merged
into the common/recovery.c
