commit 25259f7a5de2de9d67793dc584b15c83a3134c93 upstream.
This driver is an OF driver, it depends on OF, and uses TIMER_OF_DECLARE, so it should select CONFIG_TIMER_OF.
Without CONFIG_TIMER_OF enabled this can lead to warnings such as:
powerpc-linux-ld: warning: orphan section `__timer_of_table' from `drivers/clocksource/timer-microchip-pit64b.o' being placed in section `__timer_of_table'.
Because TIMER_OF_TABLES in vmlinux.lds.h doesn't emit anything into the linker script when CONFIG_TIMER_OF is not enabled.
