Subject: [PATCH] ARM: dts: rockchip: delete unused nodes for
 rv1103g-battery-ipc board

It makes sense to reduce the number of device nodes.

Before:
[    0.150197] initcall of_platform_default_populate_init+0x1/0x6a returned 0 after 13020 usecs

After:
[    0.144482] initcall of_platform_default_populate_init+0x1/0x6a returned 0 after 9765 usecs
