Subject: [PATCH] rtlwifi: rtl8192c: Change REG_C2HEVT_CLEAR and REG_USTIME_TSF

in the rtl8192ce/reg.h, REG_C2HEVT_CLEAR register's address is 0x01BF
but, vendor driver's address is 0x01AF. so i change 0x01BF to 0x01AF.
also in the rtl8192ce/reg.h, 0x0551 is REG_USTIME_TSF, but vendor driver
define REG_BCN_CTRL_1. so i change the REG_USTIME_TSF to REG_BCN_CTRL_1.

according to r8192c vendor driver, rtl8192c do not use REG_USTIME_TSF.

NACK

In the code, neither REG_C2HEVT_CLEAR nor REG_USTIME_TSF is used by either
rtl8192ce nor rtl8192cu, thus it does not matter whether the definition matches
the vendor driver or not. Making this kind of change is just churning the source
without making any real difference.

Because many of these register definitions are used by all the drivers, my plan
is to create a reg.h header in rtlwifi and eliminate most or all of the headers
now associated with each driver. When I do that, I will eliminate those
definitions that are not used by any driver, but until that part is done, I
prefer that they be left alone.
