Don't assume that gpmc_l3_clk is on, enable it before touching

Note that the current code assumes that this clock is always
enabled. We are already setting smart idle and L3 autogating
for GPMC clock in gpmc_init.

We need to set the omap_chip.oc carefully for the clocks to work.

To fix this, set the omap_chip.oc in omap3_check_features() based
on the CONTROL_IDCODE and silicon revision registers.

Also add handling for 34xx es3.1.2 as es3.1 for now.

Fixes booting on at least overo board.

Make the omap_mux_read and write available for board code,
and rename omap_mux_set_board_signals into omap_mux_write_array.
Also add the related prototypes and comments into mux.h.

In some cases we want to change the signals dynamically,
mostly for power management.

Note that we cannot use the signal names as they are set

Looks like cmdline muxing got broken at some point when we
decided to limit muxing to __init code. Currently omap_mux_entry
list is not yet initialized when we try to initialize cmdline
muxing.

Fix this by calling omap_mux_init_list() before calling
omap_mux_set_cmdline_signals().

This is broken in linux-2.6.33-rc3.

Change the definitions of __pa() and __va() to not use virt_to_phys()
and phys_to_virt(). Trivial 1:1 conversion required for the non-MMU case.

A side effect if this is that the m68knommu can now use asm/virtconvert.h
for the definition of virt_to_phys() and phys_to_virt().

Also cleaned up the definition of page_to_phys() when moving into
virtconvert.h.

When sata_promise encounters an overrun or underrun error it
translates that to a libata AC_ERR_HSM, causing a hard reset.
Since over/under-runs were thought to be rare and transient,
this action seemed reasonable.

Unfortunately it turns out that the controller throws overrun
errors when e.g. hal polls a CD or DVD writer containing blank
media, causing long sequences of hard resets and retries before
EH finally gives up.

This patch updates sata_promise to classify over/under-runs as
AC_ERR_OTHER instead. This allows libata EH and upper layers to
retry or fail the operation as they see fit without the disruption
caused by repeated hard resets.

This fixes a problem using a DVD-RAM drive with sata_promise,
reported by Thomas Schorpp. I also tested it on a DVD-RW drive.

pcibus_to_node can return -1 if we cannot determine which node a pci bus
is on. If passed -1, cpumask_of_node will negatively index the lookup array
and pull in random data:

# cat /sys/devices/pci0000:00/0000:00:01.0/local_cpus
00000000,00000003,00000000,00000000
# cat /sys/devices/pci0000:00/0000:00:01.0/local_cpulist
64-65

Change cpumask_of_node to check for -1 and return cpu_all_mask in this
case:

# cat /sys/devices/pci0000:00/0000:00:01.0/local_cpus
ffffffff,ffffffff,ffffffff,ffffffff
