MIPS: BCM63xx: Add check for NULL for clk in clk_enable

Browse source

[ Upstream commit ee9ef11bd2 ]

Check clk for NULL before calling clk_enable_unlocked where clk
is dereferenced. There is such check in other implementations
of clk_enable.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
