STDBYCFG.AVREGSD replaced by STDBYCFG.VREGSMOD

In SAM L21B the former Automatic VREG Switching Disable bit in the Standby Config register (STDBYCFG.AVREGSD) is replaced by the Voltage Regulator Standby Mode bits in the same register (STDBYCFG.VREGSMOD). This allows the user to force use of the low-power regulator in standby when SleepWalking tasks are running. This mode must only be used when SleepWalking peripherals are running on a GCLK with 32kHz source.
