The base address of each DRAM channel can be calculated from other
parameters, so does not need hard-coding. What we need is the size
of each DRAM channel and DRAM_SPARSE flag to decide the start address
of DRAM channel 1.

These files only need error number macros. Actually, IS_ERR(),
PTR_ERR(), ERR_PTR(), etc. are not useful for U-Boot. Avoid
unnecessary header includes.

Currently, memconf-sld3.c and memconf-pxs2.c duplicate the code.
There are 3 patterns in terms of MEMCONF init:
- DRAM 2 channels: LD4, sLD8, Pro4, Pro5, LD11
- DRAM 3 channels: sLD3
- DRAM 3 channels (Ch2 is disable by MEMCONF[21]): Pxs2, LD20
All of them can be moved into a single file by a little more
refactoring.

Before this commit, the Kconfig menu in mach-uniphier only allowed us
to choose one SoC to be compiled. Each SoC has its own defconfig file
for the build-test coverage. Consequently, some defconfig files are
duplicated with only the difference in CONFIG_DEFAULT_DEVICE_TREE and
CONFIG_{SOC_NAME}=y.
Now, most of board-specific parameters have been moved to device trees,
so it makes sense to include init code of multiple SoCs into a single
image as long as the SoCs have similar architecture. In fact, some
SoCs of UniPhier family are very similar:
- PH1-LD4 and PH1-sLD8
- PH1-LD6b and ProXstream2 (will be added in the upcoming commit)
This commit will be helpful to merge some defconfig files for better
maintainability.

In the Linux coding style, it is recommended to include <linux/io.h>
rather than <asm/io.h>. Follow this trend.

This code is duplicated in ph1-ld4/sg_init.c and ph1-pro4/sg_init.c.
Merge the same code into a new file, memconf.c.
The helper functions no longer have to be placed in the header file.
Also, move them into memconf.c.
