ARM: tegra: pm: Do not use ioremap for sys mem
ARMv6+ architecture does not allow ioremap on system memory.
lp0 is relocated using ioremap on DRAM. If lp0 vector start address
is in system memory then use memblock_reserve and do not relocate.
Else if it is overlapping with carveout/fb then first remove the
carveout/fb using memblock_remove and then use ioremap.
