clk: pxa mark dummy helper as 'inline'

Browse Source 
The dummy_clk_set_parent function is marked as 'static' but is
no longer referenced from the pxa25x clk driver after the last use
of the RATE_RO_OPS() macro is gone from this file, causing a
harmless build warning:

In file included from drivers/clk/pxa/clk-pxa25x.c:24:0:
drivers/clk/pxa/clk-pxa.h:146:12: error: 'dummy_clk_set_parent' defined but not used [-Werror=unused-function]

This marks the functon as 'inline', which lets the compiler simply
drop it when it gets referenced.
