[PATCH 3/9] soc: sunxi: sram: Prevent the driver from being unbound

[Samuel Holland]

This driver exports a regmap tied to the platform device (as opposed to
a syscon, which exports a regmap tied to the OF node). Because of this,
the driver can never be unbound, as that would destroy the regmap. Use
builtin_platform_driver_probe() to enforce this limitation.

Fixes: 5828729bebbb ("soc: sunxi: export a regmap for EMAC clock reg on A64")
