By using brcm/brcmfmac4354-sdio.bin from linux-firmware together with
nvram.txt from vendor firmware wifi works well on the chagall-wifi and
klimt-lte.

Describe wifi node for exynos5420-chagall-wifi and
exynos5420-klimt-wifi, and decrease available memory.

Changes in v2:
- Drop patch 1 and 3 (the latter was applied)
- Fixup patch 2 so it applies cleanly after dropping patch 1
- Link to v1: https://lore.kernel.org/r/20240130-galaxy-tab-s-cleanup-v1-0-d4e17857241d@grimler.se

The last 6 MiB are used by trustzone firmware, and cannot be used by
Linux.  Currently we are saved by that the proprietary bootloader
(sboot) passes available memory to kernel through ATAG_MEM.  Change
memory range in any case so that we do not have to rely on ATAG_MEM.

Similar fix was applied for the exynos5422 odroids in commit
6591a02e17e6 ("ARM: dts: reduce total RAM by 22 MiB for
exynos5422-odroidxu3"):
