For rtl8188ee, we pass -Idrivers/net/wireless/rtlwifi/ to gcc,
however that directy no longer exists, so evidently this option
is no longer required here and can be removed to avoid a warning
when building with 'make W=1' or 'gcc -Wmissing-include-dirs'

All of the rtlwifi family of drivers have a similar routine that acquires
the hardware info from efuse and initializes a number of variables in the
driver's private area. A common routine is created for all drivers to use.

Commit 4b9d8d67b44a ("rtlwifi: rtl8192cu: Remove unused parameter") reworked
this routine. Those changes were later reverted by commit d3feae41a347
("rtlwifi: Update power-save routines for 062814 driver").
There were two changes in commit 4b9d8d67b44a. The first of these removed
a parameter from rtl_ps_set_rf_state() that was always false. This is the
change that is restored in the current patch. A second change that reworked
the locking is still being analyzed.
In addition to removing the unused parameter, there is no need for
rtl_ps_set_rf_state() to be exported.

There are nine copies of the _rtl88ee_read_adapter_info() function,
and most but not all of them cause a build warning in some configurations:
rtl8192de/hw.c: In function '_rtl92de_read_adapter_info':
rtl8192de/hw.c:1767:12: error: 'hwinfo' may be used uninitialized in this function [-Werror=maybe-uninitialized]
rtl8723ae/hw.c: In function '_rtl8723e_read_adapter_info.constprop':
rtlwifi/rtl8723ae/hw.c:1654:12: error: 'hwinfo' may be used uninitialized in this function [-Werror=maybe-uninitialized]
The problem is that when rtlefuse->epromtype is something other than
EEPROM_BOOT_EFUSE, the rest of the function uses undefined data, resulting
in random behavior later.
Apparently, in some drivers, the problem was already found and fixed
but the fix did not make it into the others.
This picks one approach to deal with the problem and applies identical
code to all 9 files, to simplify the later consolidation of those.

Commit 49f86ec21c01 ("rtlwifi: Change long delays to sleeps") was correct
for most cases; however, driver rtl8192ce calls the affected routines while
in atomic context. The kernel bug output is as follows:

To fix this bug, three of the changes from delay to sleep are reverted.
Unfortunately, one of the changes involves a delay of 50 msec. The calling
code will be modified so that this long delay can be avoided; however,
this change is being pushed now to fix the problem in kernel 4.6.0.

rtl_lps_enter does two successive check for cnt_after_linked
to make sure some time has elapsed after linked. The second
check isn't necessary, because if cnt_after_linked is bigger
than 5, it is bigger than 2 of course!
This patch remove the second check code.

What about if "rtlphy->pwrgroup_cnt" is 2? In that case we would use an
uninitialized "chnlgroup" variable and probably crash. Maybe that can't
happen for some reason which is not obvious but in that case this patch
is harmless.
Setting it to zero seems like a standard default in the surrounding code
so it's probably fine here as well.
