In many of clk_disable() implementations, it is a no-op for a NULL
pointer input, but this is one of the exceptions.
Making it treewide consistent will allow clock consumers to call
clk_disable() without NULL pointer check.

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'

The Broadcom BCM3368 Cable Modem SoC is extremely similar to the
existing BCM63xx DSL SoCs, in particular BCM6358, therefore little effort
in the existing code base is required to get it supported. This patch adds
support for the following on-chip peripherals:
- two UARTS
- GPIO
- Ethernet
- SPI
- PCI
- NOR Flash
The most noticeable difference with 3368 is that it has its peripheral
register at 0xfff8_0000 we check that separately in ioremap.h. Since
3368 is identical to 6358 for its clock and reset bits, we use them
verbatim.

Add some mosty unused, but missing clocks for BCM6328 and BCM6362.
This also fixes PCIe init on BCM6362.

All the header file does is provide the internal structure of clk,
which shouldn't be used by anyone except clk.c itself anyway.

Add a PCIe clock and use that instead of directly touching the clock
control register. While at it, fail if there is no such clock.

This module is only available on BCM6368 so far and does not require
resetting the block.
