[PATCH V2 linux-next] hwrng: update Freescale i.MX RNGA Random Number Generator

[PATCH V2 linux-next] hwrng: update Freescale i.MX RNGA Random Number Generator

[Fabian Frederick]

We can directly depend on SOC_IMX31 since commit c9ee94965dce
("ARM: imx: deconstruct mxc_rnga initialization")

Since that commit, CONFIG_HW_RANDOM_MXC_RNGA could not be switched on
with unknown symbol ARCH_HAS_RNGA and mxc-rnga.o can't be generated with
ARCH=arm make M=drivers/char/hw_random
Previously, HW_RANDOM_MXC_RNGA required ARCH_HAS_RNGA
which was based on IMX_HAVE_PLATFORM_MXC_RNGA  && ARCH_MXC.
IMX_HAVE_PLATFORM_MXC_RNGA  was based on SOC_IMX31.

Fixes: c9ee94965dce ("ARM: imx: deconstruct mxc_rnga initialization")
