[PATCH 1/2] ARM: shmobile: r8a7790: smp: remap whole apmu region

[PATCH 1/2] ARM: shmobile: r8a7790: smp: remap whole apmu region

[Wolfram Sang]

From: Wolfram Sang <wsa+renesas@sang-engineering.com>

Documentation says the last register is at 0x184 (CAxCPUCMCR), so use
proper length. Current APMU code accesses CAxCPUnCR which is currently
outside of the remapped area.

Thanks, and sorry for letting this slip.
I have queued up this and the subsequent patch for v3.21.
