INAGAKI Hiroshi 10a674d277 ath79: fix initramfs execution for NEC Aterm devices
Fix execution of initramfs image on NEC Aterm devices by increasing
available memory for lzma extraction of lzma-loader.

The size of initramfs image of v24.10.0 exceeds available memory
(LZMA_TEXT_START - LOADADDR) and loader data running at LZMA_TEXT_START
will be overwritten by extracted data. As a result, LZMA extraction will
be broken and stuck (or unexpectedly reset).
Fix that issue by setting higher LZMA_TEXT_START address to increase
available memory for LZMA extraction by lzma-loader.

log (v24.10.0):
