v5:
 - No change.

v4:
 - Fix hw.h header guard.
 - Use more bit definitions.
 - Remove unnecessary parentheses.
 - Rename delay to retry.
 - Adjust whitespace.
 - Initialise variable retry.
 - Replace the global variables with members of rtl_priv:
	curveindex_2g
	curveindex_5g
	mutex_for_hw_init (used to be globalmutex_for_power_and_efuse)
	mutex_for_power_on_off (used to be globalmutex_power)
 - Delete globalmutex_for_mac0_2g_mac1_5g. Extend mutex_for_hw_init's
   critical section instead.
 - Add empty lines for better readability.

v3:
 - No change.

v2:
 - Patch is new in v2, split from patch 3/3 in v1.
