msm8974: init: Call eMMC recovery init

Calling eMMC recovery common function in recovery code will give as
a way to distinguish what booting to proceed. There are two options
to boot - normal boot using kernel and ramdisk from boot partition
and recovery boot using kernel and ramdisk from recovery eMMC
partition. The decision is made from the common code in recovery.c
checking for boot-recovery message from misc partition.
