Tony Lindgren e9b7086b80 ARM: OMAP: Fix reprogramming of dpll1 rate 
Commit a66cb3454f (ARM: OMAP: Map SRAM
later on with ioremap_exec()) moved the SRAM init to happen later
to remove a dependency to early SoC detection for map_io.

This broke booting on some boards not using Kconfig option for
OMAP_CLOCKS_SET_BY_BOOTLOADER as the dpll1 reprogramming would
cause the following error:

kernel BUG at arch/arm/plat-omap/sram.c:226!

Code: 0a000002 e1a0e00f e12fff13 e89da800 (e7f001f2)

Fix this by adding omap1_clk_late_init() that only reprograms dpll1
if the bootloader rate is less than 60MHz. This also allows removing
of the OMAP_CLOCKS_SET_BY_BOOTLOADER option.
