arch: cxd56xx: Introduce CXD56_PHYSADDR
Summary:
- This commit converts data to the physical address for DMA transfer.
Impact:
- cxd56_dmac.c, cxd56_sdhci.c, cxd56_usbdev.c
- cxd56_cisif.c, cxd56_emmc.c, cxd56_ge2d.c, cxd56_udmac.c
Testing:
- Tested with following configurations
- spresense:wifi, spresense:wifi_smp, spresense_rndis, spresense_rndis_smp
- NOTE: additional commits are needed for the test
- NOTE: cxd56_cisif.c, cxd56_emmc.c, cxd56_ge2d.c, cxd56_udmac.c are not tested
