Luca Coelho 99be6166a4 iwlwifi: pcie: recognize NICs with hw_rev 0x364 correctly 
Some devices with PCI ID 0x2723, which is supposed to be 22260, are
actually not.  So we need to differentiate them by checking the hw_rev
and change the cfg accordingly.

* CSR (control and status registers)

* CSR registers are mapped directly into PCI bus space, and are accessible
* whenever platform supplies power to device, even when device is in
* low power states due to driver-invoked device resets
* (e.g. CSR_RESET_REG_FLAG_SW_RESET) or uCode-driven power-saving modes.
*
* Use iwl_write32() and iwl_read32() family to access these registers;
* these provide simple PCI bus access, without waking up the MAC.
* Do not use iwl_write_direct32() family for these registers;
* no need to "grab nic access" via CSR_GP_CNTRL_REG_FLAG_MAC_ACCESS_REQ.
* The MAC (uCode processor, etc.) does not need to be powered up for accessing
* the CSR registers.
*
* NOTE: Device does need to be awake in order to read this memory
* via CSR_EEPROM and CSR_OTP registers
