Several drivers use the clk_{set,round}_rate() functions
that need to be defined in the platform's clock code.
The Broadcom BCM63xx platform hardcodes the clock rate so
we create new clk_{set,round}_rate() functions
which just return 0 like those in include/linux/clk.h
for the common clock framework do.

Also fixes the following build problem on a randconfig:
drivers/built-in.o: In function `nop_usb_xceiv_probe':
phy-nop.c:(.text+0x3ec26c): undefined reference to `clk_set_rate'

Changes since v1:
- Return 0 instead of -EINVAL for clk_set_rate to be compatible with
the common clock framework interfaces
- Add dummy clk_round_rate
