Revert "ramips: add support for ipTIME AX2004M"

Commit f4a79148f8cb ("ramips: add support for ipTIME AX2004M") seems to
leak KERNEL_LOADADDR 0x82000000 to other devices, causing the to no
longer boot. The leak is visible in u-boot:

   Using 'config-1' configuration
   Trying 'kernel-1' kernel subimage
     Description:  MIPS OpenWrt Linux-5.10.92
     Type:         Kernel Image
     Compression:  lzma compressed
     Data Start:   0x840000e4
     Data Size:    10750165 Bytes = 10.3 MiB
     Architecture: MIPS
     OS:           Linux
     Load Address: 0x82000000
     Entry Point:  0x82000000

Normally, it should look like this:

   Using 'config-1' configuration
   Trying 'kernel-1' kernel subimage
     Description:  MIPS OpenWrt Linux-5.10.92
     Type:         Kernel Image
     Compression:  lzma compressed
     Data Start:   0xbfca00e4
     Data Size:    2652547 Bytes = 2.5 MiB
     Architecture: MIPS
     OS:           Linux
     Load Address: 0x80001000
     Entry Point:  0x80001000

Revert the commit to avoid more people soft-bricking their devices.

This reverts commit f4a79148f8cbb7dfbcddfb0c1128caec45a01596.
