microblaze: Remove early printk call from cpuinfo-static.c

[ Upstream commit 58d647506c92ccd3cfa0c453c68ddd14f40bf06f ]

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
("microblaze: Remove early printk setup").
