OMAP3: cpuidle: Add valid field into C-state parameter passing

Different boards benefit differently from the available
seven C-states for cpu idle. In most cases, only few,
properly spaced (in terms of consumption and latency)
C-states are required to make the power management
optimal. Hence we need a possibility to pass which
C-states are actually used for each board.

So added the valid field to cpuidle_params and added
support to 3430sdp, which uses the paramenter passing.

OMAP3: cpuidle: configure latencies/thresholds from board file

The CPUidle C state latencies and thresholds are dependent on various
board specific details.  This patch makes it possible to configure
these values from the respective board files.

omap3_pm_init_cpuidle() can now be optionally called from board files
to pass board specific cpuidle parameters.  If the board files do not
use this function to pass the params default values are used which
might cause higher consumption dur to wrong state selection by the
governor.

This patch only updates the 3430sdp board files to use
omap3_pm_init_cpuidle().

From Kalle, in addition to original patch from Rajendra:

uart fifo read abort. "ce13d4716a276f4331d78ba28a5093a63822ab95"

OMAP3630 and OMAP4430 UART IP blocks have a restriction on TX FIFO
too. If you try to write to the tx fifo when it is full, the system aborts.

More details on this thread are here:
http://www.mail-archive.com/linux-omap@vger.kernel.org/msg19447.html

This can be easily reproducible by not suppressing interconnect errors or
long duration testing where continuous prints over console from multiple
threads. This patch is addressing the issue by ensuring that write is
not issued while fifo is full. A timeout is added to avoid any hang
on fifo-full for 10 mS which is unlikely case.

uart fifo read abort. "ce13d4716a276f4331d78ba28a5093a63822ab95"

OMAP3630 and OMAP4430 UART IP blocks have a restriction on TX FIFO
too. If you try to write to the tx fifo when it is full, the system aborts.

More details on this thread are here:
http://www.mail-archive.com/linux-omap@vger.kernel.org/msg19447.html

This can be easily reproducible by not suppressing interconnect errors or
long duration testing where continuous prints over console from multiple
threads. This patch is addressing the issue by ensuring that write is
not issued while fifo is full. A timeout is added to avoid any hang
on fifo-full for 10 mS which is unlikely case.

Patch is validated on OMAP3630 and OMAP4 SDP.

V2 version removed the additional 1 uS on every TX as per
Tony's suggestion

omap4: multi-omap: Allow build to work

The musb support is enabled in omap3 platforms. For omap4 only board
support is available and the driver still isn't supported.
Because of this build with omap3_defconfig used for multi-omap
doesn't work on omap4430 sdp.

This patch avoids usb_musb_init() by adding a cpu check
in the board file.

Thanks to Anand Gadiyar and Mankad Maulik for the suggestion
of patching board file instead of musb driver.
