hw/misc: Set valid access size for Exynos4210 RNG
The Exynos4210 RNG module requires 32-bit (4-byte) accesses to its registers.
According to the User Manual Section 25.3[1], the registers for RNG operations
are 32-bit. This change ensures that the memory region operations for the
RNG module enforce the correct access sizes, preventing invalid memory accesses.
