clk_add_alias is commonly called for platform devices that are not yet
registered in the device tree. Thus the clock alias is associated with
NULL device name. Fix this by passing the device name instead of just
device pointer.

Considering the header mess ATM, it is not always possible to include
the correct header files within board code. Let's keep this simple:
<mach/pxa25x.h> - for pxa25x based platforms
<mach/pxa27x.h> - for pxa27x based platforms
<mach/pxa300.h> - for pxa300 based platforms
<mach/pxa320.h> - for pxa320 based platforms
<mach/pxa930.h> - for pxa930 based platforms
NOTE:
1. one header one board file, they are not compatible (i.e. they have
conflicting definitions which won't compile if included together).
2. Unless strictly necessary, the following header files are considered
to be SoC files use _only_, and is not recommended to be included in
board code:
<mach/hardware.h>
<mach/pxa-regs.h>
<mach/pxa2xx-regs.h>
<mach/pxa3xx-regs.h>
<mach/mfp.h>
<mach/mfp-pxa2xx.h>
<mach/mfp-pxa25x.h>

As requested by Ian make state restore only if it's requested
by platform data: some platforms do correctly save the state of
the chip during suspend/resume, but some (like tosa) incorrectly
power off the chip at suspend, so the driver supports restoring
some bits of the tc6393xb state (not full, merely enough to support
resume on tosa). With this patch this code is disabled by default.

Related to d3930614e6.
RCSR is only present on PXA2xx CPUs, not on PXA3xx CPUs. Therefore,
we should not be unconditionally writing to RCSR from generic code.
Since we now clear the RCSR status from the SoC specific PXA PM code
and before reset in the arch_reset() function, the duplication in
the corgi, poodle, spitz and tosa code can be removed.
