From: Raymond Mao <raymond.mao@riscstar.com>

Restructure K1 SoC support to handle multiple boards through a single
configuration:

1. Rename bananapi-f3_defconfig to k1_defconfig.
2. Move all K1 board files to k1 directory.
3. Rename TARGET_BANANAPI_F3 to TARGET_SPACEMIT_K1.

Eliminates the need for board-specific defconfigs while maintaining
hardware compatibility.

Signed-off-by: Raymond Mao <raymond.mao@riscstar.com>

Changes in v3:
- Use flat TARGET_SPACEMIT_K1 to avoid Kconfig recursive dependency
  caused by merge conflict with b51e59c8b34 ("riscv: Add support
  for BeagleV-Fire")
