This patchset does:
1. Moves MM related code from kernel/setup.c to mm/init.c
2. Implements compile-time fixed mappings

Using fixed mappings available, we can now get earlyprints
even without SBI calls. For example, we can use kernel
parameter "earlycon=uart8250,mmio,0x10000000" to get early
prints on QEMU virt machine without using SBI calls.

The patchset is tested on QEMU virt machine. It is based on
Linux-5.0-rc6 and can be found at riscv_fixmap_v3 branch of:
https://github.com/avpatel/linux.git.

Changes since v2:
 - Fixed commit description of PATCH6
 - Ensured commit description of all PATCH use upto 72
   characters per line

Changes since v1:
 - Use more characters per line in changelog of PATCH3
 - Removed #ifndef __ASSEMBLY__ from PATCH5
 - Use more characters per line in commets of PATCH5
 - Added PATCH6 to implement keepinitrd kernel parameter
