GPIO support for Qualcomm SOCs requires interaction with the

The 'PCOM' method of clock control (commands issued to the radio
CPU) is shared across several (but not all) Qualcomm SOCs.
Generalize this clock mechanism so these other SOCs can be added.

Some smd clients may write from multiple threads, in which case it's
not safe to call smd_write without holding a lock.  smd_write_atomic()
provides the same functionality as smd_write() but obtains the smd
lock first.

This code provides the low level interface to the "shared memory
state machine" (smsm), and the virtual serial channels (smd), used
to communicate with the baseband processor.  Higher level transports
(rpc, ethernet, AT command channel, etc) ride on top of this.

Otherwise more complicated uart configuration won't be possible.
We can use r1 for tmp register for both head.S and debug.S.

NOTE: This patch depends on another patch to add the the tmp register
into all debug-macro.S files. That can be done with:

$ sed -i -e "s/addruart,rx|addruart, rx/addruart, rx, tmp/"

OMAP wishes to pass state to the boot loader upon reboot in order to
instruct it whether to wait for USB-based reflashing or not.  There is
already a facility to do this via the reboot() syscall, except we ignore
the string passed to machine_restart().

This patch fixes things to pass this string to arch_reset().  This means
that we keep the reboot mode limited to telling the kernel _how_ to
perform the reboot which should be independent of what we request the
boot loader to do.

Let's provide an overridable default instead of having every machine
class define __virt_to_bus and __bus_to_virt to the same thing.  What
most platforms are using is bus_addr == phys_addr so such is the default.

One exception is ebsa110 which has no DMA what so ever, so the actual
definition is not important except only for proper compilation.  Also
added a comment about the special footbridge bus translation.

Let's also remove comments alluding to set_dma_addr which is not
(and should not) be commonly used.
