- Added wfe and iomb functions for riscv
- Added memory port to system port and system port to memory port
  conversion macros to access uncached memory through system port
- Modified pte_pfn and pfn_pte functions
  To access uncache memory, we need to remap physical address to system
  port address. System port pfn address will be stored in pte if uncached
  bit is set.

The EIC7700 has non-coherent DMAs but predate the standard RISC-V
Zicbom extension, so instead we need to use this cache controller
for non-standard cache management operations

Enabled all available cache ways to be used as cache.
This change is required for CPU performance improvement.

Out of reset, only way 0 is enabled and the disabled ways
are addressable in L2-LIM(Loosely Integrated Memory).

  while dma0 havn't. Since dma cfg clk is default on we do not
  need to control it
- Add arst and prst reset control
