arm64: fix undefined reference to 'printk'
The printk symbol was intended as a generic address that is always
exported, however that turned out to be false with CONFIG_PRINTK=n:
ERROR: "printk" [arch/arm64/kernel/arm64-reloc-test.ko] undefined!
This changes the references to memstart_addr, which should be there
regardless of configuration.
Fixes: a257e02579e4 ("arm64/kernel: don't ban ADRP to work around Cortex-A53 erratum #843419")
