clocksource/drivers/ixp4xx: Select TIMER_OF when needed

[ Upstream commit 7a3b8758bd6e45f7b671723b5c9fa2b69d0787ae ]

Compile-testing the ixp4xx timer with CONFIG_OF enabled but
CONFIG_TIMER_OF disabled leads to a harmless warning:

arm-linux-gnueabi-ld: warning: orphan section `__timer_of_table' from `drivers/clocksource/timer-ixp4xx.o' being placed in section `__timer_of_table'

Move the select statement from the platform code into the driver
so it always gets enabled in configurations that rely on it.
