[PATCH -next] mips: Enable common clock framework for malta and sead3

[Guenter Roeck]

Since commit e69b3d70ac57 ("CLOCKSOURCE: mips-gic: Update clockevent
frequency on clock rate changes"), malta_defconfig and sead3_defconfig
fail to build as follows.

drivers/clocksource/mips-gic-timer.c: In function 'gic_clk_notifier':
drivers/clocksource/mips-gic-timer.c:102:16:
	error: 'POST_RATE_CHANGE' undeclared
drivers/clocksource/mips-gic-timer.c:103:48:
	error: dereferencing pointer to incomplete type
drivers/clocksource/mips-gic-timer.c: In function 'gic_clocksource_of_init':
drivers/clocksource/mips-gic-timer.c:209:3:
	error: implicit declaration of function 'clk_notifier_register'

Fix by enabling COMMON_CLK for both configurations. Build tested for
malta_defconfig and sead3_defconfig. Tested with qemu malta emulation.

Fixes: e69b3d70ac57 ("CLOCKSOURCE: mips-gic: Update clockevent frequency on clock rate changes")
