Samuel Holland bbf3bb6dde riscv: Allow NOMMU kernels to access all of RAM
[ Upstream commit 2c0391b29b ]

NOMMU kernels currently cannot access memory below the kernel link
address. Remove this restriction by setting PAGE_OFFSET to the actual
start of RAM, as determined from the devicetree. The kernel link address
must be a constant, so keep using CONFIG_PAGE_OFFSET for that purpose.
