[ Upstream commit 0075df288dd8a7abfe03b3766176c393063591dd ]
Before commit 721f4a6526da ("mm/memblock: remove empty dummy entry") the
check for non-zero of memblock.reserved.cnt in mmu_init() would always
be true either because memblock.reserved.cnt is initialized to 1 or
because there were memory reservations earlier.
The removal of dummy empty entry in memblock caused this check to fail
because now memblock.reserved.cnt is initialized to 0.
Remove the check for non-zero of memblock.reserved.cnt because it's
perfectly fine to have an empty memblock.reserved array that early in
boot.

Early printk has been removed already that's why also remove calling it.
Similar change has been done in cpuinfo-pvr-full.c by commit cfbd8d1979af

[ Upstream commit edc66cf0c4164aa3daf6cc55e970bb94383a6a57 ]
early_printk support for removed long time ago but compilation flag for
ftrace still points to already removed file that's why remove that line
too.
