All MStar v7 SoCs have an internal SRAM region that is between 64KB
(infinity2m) and 128KB(infinity3, mercury5).

The region is always at the same base address and is used for the
second stage loader (MStar IPL or u-boot SPL) and will be used for
the DDR self-refresh entry code within the kernel eventually.

This patch adds a 128KB region to the SoC and the minimum 64KB SRAM
region to the base dtsi. Families with more SRAM will override the
size in their family level dtsi.

This userspace program includes UAPI headers exported to usr/include/.
'make headers' always works for the target architecture (i.e. the same
architecture as the kernel), so the sample program should be built for
the target as well. Kbuild now supports 'userprogs' for that.

I also guarded the CONFIG option by 'depends on CC_CAN_LINK' because
$(CC) may not provide libc.

This reverts commit e0b250b5,
which broke build systems that need to install files to a certain
path, but do not set INSTALL_MOD_PATH when invoking 'make install'.

  $ make INSTALL_PATH=/tmp/destdir install
  mkdir: cannot create directory ‘/lib/modules/5.8.0-rc1+/’: Permission denied
  Makefile:1342: recipe for target '_builtin_inst_' failed
  make: *** [_builtin_inst_] Error 1

While modules.builtin is useful also for CONFIG_MODULES=n, this change
in the behavior is quite unexpected. Maybe "make modules_install"
can install modules.builtin irrespective of CONFIG_MODULES as Jonas
originally suggested.

Anyway, that commit should be reverted ASAP.
