[PATCH v1] ARM: mstar: Drop OF node references after mapping

[Yuho Choi]

of_find_compatible_node() returns a device node with its reference
count incremented. of_iomap() uses the node to map the register range,
but does not consume that reference.

Drop the node references after mapping the smpctrl and l3bridge
registers.

Fixes: 312b62b6610c ("ARM: mstar: Add machine for MStar/Sigmastar Armv7 SoCs")
Fixes: 5919eec0f092 ("ARM: mstar: SMP support")
