In the function ixgbe_get_swfw_sync_semaphore, an incorrect
check was treating success as failure and vice-versa. This led
to manipulating the IXGBE_SWFW_SYNC register without holding
the software semaphore first, which is an error. In addition,
if getting the REGSMP bit in the IXGBE_SW_FW_SYNC register
timed out, no error code would be returned, making the caller
think that it had successfully acquired the lock. Fix both of
those issues and clean up the function a bit, such as make the
name in the comment match the function.

Failure to acquire the semaphore would lead to a spurious release
of the semaphore in several functions. Do not release a semaphore
that you did not get.

The only slightly controversial one is the change to use GB for the

Enable ARMCLK down feature on all Exynos4 SoCs. The frequency of
ARMCLK will be reduced upon entering idle mode (WFI or WFE).
The feature behaves like very fast cpufreq ondemand governor. In idle
mode this reduces energy consumption on full frequency chosen by
cpufreq governor by approximately:
- Trats2: 6.5% (153 mA -> 143 mA)
- Trats: 33.0% (180 mA -> 120 mA)
- Gear1: 27.0% (180 mA -> 130 mA)
The patch uses simillar settings as Exynos5250 (clk-exynos5250.c),
except it disables clock up feature and on Exynos4412 ARMCLK down is
enabled for all 4 cores.
Tested on Trats board (Exynos4210), Trats2 board (Exynos4412) and
Samsung Gear 1 (Exynos4212).

Now that the protocol is part of the scancode, it is pretty easy to merge
the rc5 and streamzap decoders. An additional advantage is that the decoder
is now stricter as it waits for the trailing silence before determining that
a command is a valid rc5/streamzap command (which avoids collisions that I've
seen with e.g. Sony protocols).
