Fix RISC-V configMTIMECMP_BASE_ADDRESS (64-bit) stored in 32-bit int (#1176)

Browse Source 
Related to #189

Update `configMTIMECMP_BASE_ADDRESS` to be stored in a 64-bit integer.

* Change the type of `ullMachineTimerCompareRegisterBase` to `uint64_t` in `portable/GCC/RISC-V/port.c`.
* Change the type of `ullMachineTimerCompareRegisterBase` to `uint64_t` in `portable/IAR/RISC-V/port.c`.
* Update the initialization of `ullMachineTimerCompareRegisterBase` to use `configMTIMECMP_BASE_ADDRESS` in both files.
