Subject: [PATCH] ARM: imx: replace width with mask for clk_busy_mux

The recent addition of table-based parent lookups[1] in the common
clk_mux implementation removed the width member of struct clk_mux and
replaced it with an arbitrary mask.  This broke compilation for i.MX
platforms using clk_busy_mux which builds upon the common clk_mux.

Fixed by populating the mask member during clk_busy_mux registration
instead of the now non-existent width member.
