[PATCH v4 05/11] rockchip: rock5a-rk3588s: use DRAM banks from ATAGS

From: Quentin Schulz <quentin.schulz at theobroma-systems.com>
RK3588-based devices now support creating DRAM banks with proper holes
by reading the ATAGS from Rockchip TPL blob, so let's use that mechanism
instead.
Since ft_board_setup isn't defined anymore, there's no need for
selecting CONFIG_OF_BOARD_SETUP.
Similarly, because the rock5a-rk3588s.c would be empty, it is simply
removed, with the (would-be-empty) Makefile as well.
The CONFIG_NR_DRAM_BANK now defaults to 10 which is a safe bet for
reading banks from ATAGS, so let's use the default value instead.
