[PATCH 3/4] ARM: OMAP: Remove MPU-timer based sched_clock()

[Kevin Hilman <khilman@mvista.com>]

[-- Attachment #1: remove-MPU-sched-clock.patch --]
[-- Type: text/plain, Size: 1069 bytes --]

Remove MPU-timer based sched_clock() in favor of the common one based
on 32k sync timer which works across all OMAP1/2/3 platforms.

Using 32k based one also gives a valid sched_clock() very early in the
boot process.
