This follows update of UTCPD.VBSCALE register field. It supports:
- "divide-20": External VBUS voltage divider circuit should be 1/20
for EPR application. The divided voltage compares with
200mV to set or clean VBUS Present bit.
- "divide-10": External VBUS voltage divider circuit should be 1/10
for SPR application. The divided voltage compares with
400mV to set or clean VBUS Present bit.
