Subject: [PATCH_V2 12/34] MIPS: jz4740: call jz4740_clock_init earlier

From: Paul Burton <paul.burton@...tec.com>

Call jz4740_clock_init before any uses of jz4740_clock_bdata occur. This
is in preparation for replacing uses of that struct with calls to
clk_get_rate, which will allow the clocks to be migrated towards common
clock framework & devicetree.
