power: supply: ucs1002: Adjust ucs1002_set_usb_type() to accept string values

power_supply_sysfs.c accept wrrites of strings to "usb_type" for strings
values matching an entry in POWER_SUPPLY_USB_TYPE_TEXT[]. If such a
string value is written then the int value passed to ucs1002_set_property()
will be an enum power_supply_usb_type value.

Before this change ucs1002_set_usb_type() expected the value to be an index
into ucs1002_usb_types[]. Adjust ucs1002_set_usb_type() to use the enum
value directly so that writing string values works.

The list of supported types in ucs1002_usb_types[] is: PD, SDP, DCP, CDP.
The [POWER_SUPPLY_USB_TYPE_]SDP, DCP and CDP enum labels have a value of
1, 2 and 3. So userspace selecting SDP, DCP or CDP by writing 1, 2 or 3
will keep working. POWER_SUPPLY_USB_TYPE_PD which is mapped to the ucs1002
dedicated mode however has a value of 6. Before this change writing 0 would
select the dedicated mode. To preserve userspace API compatibility also map
POWER_SUPPLY_USB_TYPE_UNKNOWN (which is 0) to the dedicated mode.
