ath11k_nss: Revert setting fw_mem_mode for IPQ807x

Leave it set to '0', as it will kernel panic with 2K skb patch. This
flag was incorrectly assumed to save memory on 1G platforms.

ath11k_nss: remove leftover max_tx_ring

it was not removed when applying patch to replace it with 'max_tx_ring =
DP_TCL_NUM_RING_MAX +1'

ath11k_nss: Import bugfix patches

ath11k_nss: Experimental build for IPQ6018

This will require setting the correct `ATH11K_MEM_PROFILE_XXX` for your
platform. Setting it to value lower/higher than physically available
will cause NULL virtual address kernel panics.

I believe this setting was not originally meant to reduce memory
footprint of 1G+ platforms, but to account for platforms that were
512M or less.

Will require tweaking to allow for the old behvaior on 1G+ IPQ807x,
while still saving memory for platforms <= 512M.
