93565cc94c arm: mach-rmobile: Drop <common.h>
For most source files we can just drop <common.h>. We need to add an
include for <asm/u-boot.h> in a couple of places. Also sort the include
list in memmap-gen3.c while we're here.

eb4f1246f9 arm: rmobile: Support RZ/G2L memory map
The memory map for the RZ/G2L family differs from that of previous R-Car
Gen3/Gen4 SoCs.

A high level memory map can be seen in figure 5.2 (section 5.2.1) of the
RZ/G2L data sheet rev 1.30 published May 12, 2023. A summary is included
here (note that this is a 34-bit address space):
  * 0x0_0000_0000 - 0x0_0002_FFFF SRAM area
  * 0x0_0003_0000 - 0x0_0FFF_FFFF Reserved area
  * 0x0_1000_0000 - 0x0_1FFF_FFFF I/O register area
  * 0x0_2000_0000 - 0x0_2FFF_FFFF SPI Multi area
  * 0x0_3000_0000 - 0x0_3FFF_FFFF Reserved area
  * 0x0_4000_0000 - 0x1_3FFF_FFFF DDR area (4 GiB)
  * 0x1_4000_0000 - 0x3_FFFF_FFFF Reserved area

Within the DDR area, the first 128 MiB are reserved by TrustedFirmware.
The region from 0x43F00000 to 0x47DFFFFF inclusive is protected for use
in TrustedFirmware/OP-TEE, but all other memory is included in the
memory map. This reservation is the same as used in R-Car
Gen3/Gen4 and RZ/G2{H,M,N,E} SoCs.

DRAM information is initialised based on the data in the fdt.
