ath79: fix initramfs boot for Huawei AP5030DN and AP6010DN

Browse Source 
Fix execution of initramfs image on Huawei AP5030DN and AP6010DN by
increasing available memory for LZMA extraction by the loader.

The default leaves only ~23.6 MB between the decompression target
and the running loader code. Extracting images with built-in
packages lead to overwriting the loader code. This causes
the decompression to produce garbage output and hang.

Fix this by overwriting LZMA_TEXT_START to increase the
available memory for LZMA extraction to ~39.6 MB.
