qcacmn: Allow only 80P80 supported frequencies for 130 opclass

Pine and Spruce supports 80P80 mode of operation in 5 GHz band
and hence opclass 130 is sent to the user application in
MESH_MAP_OPCLASS_FOR_CUR_HWMODE NL80211 command.
However, these chips support 80P80 mode of operation
only on CFI 138 and 155, but to the application all the 80 MHz
channels in the 5 GHz band are advertised as supported.
This causes the application's channel selection algorithm to fail.
The existing API reg_is_chan_supported() can determine if the input
frequency is 80P80 capable only if cfreq2 of the 80P80 channel is
provided and in reg_get_cfis_from_opclassmap_for_non6g() API, it is not
possible to determine all combinations of cfreq2 for the given primary
frequency. Hence, a call to is_freq_80p80_supported() is made to
determine if any 80P80 combination is possible for the given input
frequency.
Also, 6 GHz channels do not support 80P80 mode of operation.
reg_is_cfi_supported() does a lot of computation to find out that
80P80 is not supported. Hence, if the opclass entry
is 6 GHz 80P80, set 80p80_supported as false.

Hence, send only the supported 80P80 CFIs in the
supported channel list array in MESH_MAP_OPCLASS_FOR_CUR_HWMODE command.
