Subject: [PATCH on kgene/for-next] ARM: EXYNOS: Do not calculate boot address
 twice

Commit b3205dea8fbf ("ARM: EXYNOS: Map SYSRAM through generic DT
bindings") introduced local variable boot_reg where boot address from
cpu_boot_reg() call is stored. Re-use it instead calling cpu_boot_reg()
again.
