Instead of reading bit 9 of RFPGA0_XA_HSSIPARAMETER2 every time a frame
is received, just use rtlphy->cck_high_power, which is initialised in
_rtl92d_phy_bb_config(). That bit never changes anyway.
With this change _rtl92de_query_rxphystatus() can be shared with the
upcoming USB driver. The USB driver can't read registers in this
function because register reading can sleep.
Compile tested only.

"That bit never changes anyway." <- I'm 99% sure this is true.
