ath11k_nss: allow specifying pbuf 'memory_profile'

In case you want to specify the memory profile to use rather than
letting it autodetect. The following new uci option is introduced.
pbuf.

config general opt
  option memory_profile ''

choices are 1gb, 512mb, 256mb. Delete option to let it autodetect.

NOTE: You must reboot after changing these settings, for it to
autoapply.
