arm64: mm: Move reserve_crashkernel() into mem_init()

Browse Source 
commit 0a30c53573b07d5561457e41fb0ab046cd857da5 upstream

crashkernel might reserve memory located in ZONE_DMA. We plan to delay
ZONE_DMA's initialization after unflattening the devicetree and ACPI's
boot table initialization, so move it later in the boot process.
Specifically into bootmem_init() since request_standard_resources()
depends on it.
