[ Upstream commit 3a89b6dec9920026eaa90fe8457f4348d3388a98 ]
The 2.7.0 series of QCN9074's firmware requests 5 segments of memory instead of 3 (as in the 2.5.0 series).
The first segment (11M) is too large to be kalloc'd in one go on x86 and requires piecemeal 1MB allocations, as was the case with the prior public firmware (2.5.0, 15M).
Since f6f92968e1e5, ath11k will break the memory requests, but only if there were fewer than 3 segments requested by the firmware. It seems that 5 segments works fine and allows QCN9074 to boot on x86 with firmware 2.7.0, so change things accordingly.
