a74c28a0f2 ARM: uniphier: introduce flags to uniphier_board_data structure
I need to add more board attributes, so the "flags" member will be
handier than separate boolean ones.

4e3d84066e ARM: uniphier: use (devm_)ioremap() instead of map_sysmem()
This does not have much impact on behavior, but makes code look more
more like Linux.  The use of devm_ioremap() often helps to delete
.remove callbacks entirely.

0586e22783 ARM: uniphier: rename umc-ld20-regs.h to umc64-regs.h
This header will be shared between PH1-LD11 and PH1-LD20
(and hopefully new ARMv8 SoCs developed in the future),
so umc64-regs.h would be a better fit.

94b756f331 ARM: uniphier: refactor UMC init code for ProXstream2
Currently, a dummy value is defined for the UMC_SPCCTLA register
when the DRAM size is zero.  This seems weird because the controller
does not need setting in the first place if the size is zero.

Also, redefine enum dram_size to represent the DRAM size per 16-bit
unit.  This makes things simpler because the channel 0 and 1 are
connected with 32-bit width DRAM, while the channel 2 is connected
with 16-bit width one.

I am renaming SIZE_* into DRAM_SZ_* (and also FREQ_* to DRAM_FREQ_*
for consistency) while I am here because SIZE_* might be easily
mixed-up with the macros in include/linux/sizes.h.
