Subject: [PATCH] ieee802154: don't select COMMON_CLK

A device driver must not select the COMMON_CLK subsystem, as that conflicts
with platforms that provide a legacy implementation of the clk API:

drivers/clk/clk.o: In function `clk_enable':
clk.c:(.text.clk_enable+0x0): multiple definition of `clk_enable'
arch/arm/mach-sa1100/clock.o:clock.c:(.text.clk_enable+0x0): first defined here
drivers/clk/clk.o: In function `clk_round_rate':
clk.c:(.text.clk_round_rate+0x0): multiple definition of `clk_round_rate'
arch/arm/mach-sa1100/clock.o:clock.c:(.text.clk_round_rate+0x0): first defined here
drivers/clk/clk.o: In function `clk_get_parent':
clk.c:(.text.clk_get_parent+0x0): multiple definition of `clk_get_parent'
arch/arm/mach-sa1100/clock.o:clock.c:(.text.clk_get_parent+0x0): first defined here
drivers/clk/clk.o: In function `clk_get_rate':
clk.c:(.text.clk_get_rate+0x0): multiple definition of `clk_get_rate'

This changes the 'select' into 'depends on', as all other similar drivers do.
