As exposed by "make randconfig", some symbols such as
XILINX_MICROBLAZE0_PVR can be set without TARGET_MICROBLAZE_GENERIC but
have a transitive dependency on it. The easiest path of resolution here
is that since there is only one valid microblaze "board", rework that
symbol to be non-optional.

The help for CONFIG_MTD explains that it needs to be enabled for various
things like NAND, etc to be available. It however then doesn't enforce
this dependency and so if you have none of these systems present you
still need to disable a number of options. Fix this by making places
that select/imply one type of flash, but did not do the same, also do
this for "MTD". Make boards which hadn't been enabling MTD already but
need it now, do so. In a few places, disable CONFIG_CMD_MTDPARTS as it
wasn't previously enabled but was now being implied.

Microblaze and m68k are the only remaining architectures that still enable
CONFIG_NEEDS_MANUAL_RELOC by default.

Microblaze has had runtime relocation support using CONFIG_STATIC_RELA for
quite some time, since commit d58c007498 ("microblaze: Add support for run
time relocation"). Drop support for CONFIG_NEEDS_MANUAL_RELOC and make
runtime relocation the default, as the rest of the architectures do.

Replace CONFIG_ICACHE with a Kconfig option more limited in scope -
XILINX_MICROBLAZE0_USE_WIC. It should be enabled if the processor supports
the "wic" (Write to Instruction Cache) instruction. It will be used to
guard "wic" invocations in microblaze cache code.

Replace CONFIG_DCACHE with a Kconfig option more limited in scope -
XILINX_MICROBLAZE0_USE_WDC. It should be enabled if the processor supports
the "wdc" (Write to Data Cache) instruction. It will be used to guard
"wdc" invocations in microblaze cache code.

Also, drop all ifdefs around flush_cache() calls and only keep one
CONFIG_IS_ENABLED() guard within flush_cache() itself.

Microblaze is using NEEDS_MANUAL_RELOC from the beginnging. This is causing
issues with function pointer arrays which need to be updated manually after
relocation. Building code with -fPIC and linking with -pic will remove this
limitation and there is no longer need to run manual update.

By default still old option is enabled but by disabling NEEDS_MANUAL_RELOC
code will be compiled for full relocation.

The patch does couple of things which are connected to each other.
- Define STATIC_RELA dependency to call relocate-rela to fill sections.
- REMAKE_ELF was already enabled but u-boot file can't be used because
  sections are empty. relocate-rela will fill them and output file is
  u-boot.elf which should be used.
- Add support for full relocation (u-boot.elf)
- Add support for early relocation when u-boot.bin is loaded to different
  address then CONFIG_SYS_TEXT_BASE
- Add rela.dyn and dynsym sections

Disabling NEEDS_MANUAL_RELOC U-Boot size increased by 10% of it's original
size (550kB to 608kB).

Move these two options to the arch Kconfig file.
