simplify function Hal_GetChnlGroup8723B(). It returns
an unused and unnecessary bool value telling which
band the device works on. Since we work only on
2.4Ghz band and the useful return value is the
second function argument we convert the return type to
void.
remove 5Ghz dead code either (for channel > 14).

of_genpd_add_device() is called before platform_device_register(), as it
needs to attach the genpd before the device is probed. But the spinlock
is only initialized when the device is registered.
Fix this by open-coding the spinlock initialization, cfr.
device_pm_init_common() in the internal drivers/base code, and in the
SuperH early platform code.

strcpy() performs no bounds checking on the destination buffer. This
could result in linear overflows beyond the end of the buffer, leading
to all kinds of misbehaviors. The safe replacement is strscpy().

The rtl88eu_pwrseqcmdparsing function takes a parameter to restrict
commands to certain power cut versions of the rtl8188eu chipset.
This mechanism is not used, the callers always select all versions.

The driver defines a couple of "flows" to move the chip into a certain
power state. Each flow is a sequence of "transitions".
This patch removes flows and transitions which are not used.

The hal variable to trigger gpio 0 seems to be a leftover from debugging
code that was removed. An empty function is called when this variable is
written to.
Remove the empty function and the variable itself. It should be safe to
remove an entry from the hw_variables enum as this enum is used only
within the rtl8188eu driver.

Move source file hal/mac_cfg.c to the 'core' driver directory, and also
rename its array from array_MAC_REG_8188E to array_MAC_REG, as well as
renaming the function rtl88eu_phy_mac_config to phy_mac_config. Also
modify single call-site for this function to reflect new name.
This file contains no code which touches the adapter's HalData structure,
and is a good candidate for therefore moving out of 'hal'. Also, no
need for these signatures to include the model number as this driver
only supports RTL8188eu.

wpa_set_auth_algs() function contains some conditional

The while-loop only iterates once becase the post increment test of count
being non-zero is false on the first iteration because count is zero. Fix
this by using a for-loop instead. Static analysis found the issue on the
count > POLLING_LLT_THRESHOLD check always being false since the loop
currently just iterates once.
Thanks to David Laight for suggesting using for-loop instead to improve
the readability of the fix.
