ARM: shmobile: Remove legacy board code for KZM-A9-GT
The KZM-A9-GT board is sufficiently supported by DT-based and board-less
SH-Mobile AG5 (sh73a0) multiplatform kernels. Hence remove the legacy
board code to reduce maintenance effort.
Lacking areas are:
- USB (it does't work in legacy, neither),
- LCDC (the LCDC is wired to the legacy INTC, which is not planned to
be supported with DT).
- DMAC/IPMMU (no DT bindings are planned).
