arm64: dts: rockchip: Fix wrong register range of rk3576 gpu

According to RK3576 TRM part1 Table 1-1 Address Mapping, the size of
the GPU registers is 128 KB.

The current mapping incorrectly includes the addresses of multiple
following IP like the eInk interface at 0x27900000. This has not
been detected by the DT tooling as none of the extra mapped IP is
described in the upstream RK3576 DT so far.
