sh: Use clk_always_enable() on sh7722 / Migo-R / SE7722
Use clk_always_enable() on the sh7722 processor and in the board code for Migo-R and Solution Engine 7722. Remove duplicate MSTPCR register definitions. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
