* 3945 and 4965 have volatile SRAM, and must save/restore contents
* to/from host DRAM when sleeping/waking for power-saving.
* Each direction takes approximately 1/4 millisecond; with this
* overhead, it's a good idea to grab and hold MAC_ACCESS_REQUEST if a
* series of register accesses are expected (e.g. reading Event Log),
* to keep device from sleeping.
*
* CSR_UCODE_DRV_GP1 register bit MAC_SLEEP == 0 indicates that
* SRAM is okay/restored. We don't check that here because this call
* is just for hardware register access; but GP1 MAC_SLEEP check is a
* good idea before accessing 3945/4965 SRAM (e.g. reading Event Log).
