[PATCH 1/7] OMAP2xxx clock: init osc_ck, sys_ck internal lists early

[Paul Walmsley <paul@pwsan.com>]

Commit 3f0a820c4c0b4670fb5f164baa5582e23c2ef118 breaks OMAP2xxx boot
during initial propagate_rate() on osc_ck and sys_ck.  Fix by calling
clk_init_one() for these clocks first.

Resolves

<1>Unable to handle kernel NULL pointer dereference at virtual address 00000000

<1>[00000000] *pgd=00000000
