[PATCH v2] ARM: Fix build if CLKDEV_LOOKUP is not configured

[Guenter Roeck]

mips:allmodconfig fails to build with

drivers/clocksource/timer-sp804.c:
	In function '__sp804_clocksource_and_sched_clock_init':
drivers/clocksource/timer-sp804.c:88:3: error:
	implicit declaration of function 'clk_get_sys'

because CLKDEV_LOOKUP is not configured and the driver depends on it.

Fixes: 0b7402dce445 ("ARM: 8366/1: move Dual-Timer SP804 driver to
	drivers/clocksource")
