fix(rmmd): remove the assert check for RMM_BASE

Browse source 
This patch removes the assert from rmmd_setup() that checks if the
RMM image PC is equal to RMM_BASE. The RMM image can be relocated to
any address in the DRAM by the previous bootloader. So, providing the
RMM base address at compile time is not feasible for such platforms.

The assert check is now replaced with a runtime check for the RMM image.
