MTD, UBI/UBIFS sync.
Note (From Jagan): For testing raw mtd parition erase/read/write operations
using cmd_sf, sf_mtd should be required to register the spi flash device to
MTD layer but the sf_mtd_info ops were not required until and unless if we
use any flash filesystem layer say for example UBI. Due to this the foot-print
got increased ~290bytes in non-UBI case here that should be acceptible.

Some archs/boards specify their own default by pre-defining the config
which causes the Kconfig system to mix up the order of the configs in
the defconfigs... This will cause merge pain if allowed to proliferate.
Remove the configs that behave this way from the archs.
A few configs still remain, but that is because they only exist as

Patch 33fe2fb8df titled
"mmc: bcm283x: Remove get_timer_us() from mmc driver"
incorrectly replaced ad-hoc get_timer_us() function
with a plain get_timer(). The get_timer() operates in
mSec units instead of uSec though, which caused very
slow operation of the driver.
Restore the original behavior of the driver, but avoid
get_timer_us() and use timer_get_us() instead. The later
is part of the standard API.

Without this we loose every other interrupt packet. We never noticed this
because with keyboards the packets which we were loosing would normally
be key release packets.
But now that we do keyrepeat in software instead of relying on the hid
idle functionality, missing a release will result in key repeat triggering.

At present the driver does not properly honour the requested SPI CS
deactivation delay since the SPI bus is changed in the claim_bus() method.
Everything the claim_bus() method does can be done when the device is probed
(setting the speed and mode) and at the start of a new transfer (where the
fifo_status is already cleared). So drop this method.
Also, until the delay is complete, we should not touch the bus, so make sure
that spi_cs_activate() is called before other things are done in the xfer()
method.
