hwmon: (max16064) Add driver documentation

MAX16064 has its own driver, thus should have its own documentation instead of
being mentioned in the generic PMBus driver documentation.

+Description
+-----------
+
+This driver supports hardware montoring for Maxim MAX16064 Quad Power-Supply
+Controller with Active-Voltage Output Control and PMBus Interface.
+
+The driver is a client driver to the core PMBus driver.
+Please see Documentation/hwmon/pmbus for details on PMBus client drivers.
+
+
+Usage Notes
+-----------
+
+This driver does not auto-detect devices. You will have to instantiate the
+devices explicitly. Please see Documentation/i2c/instantiating-devices for
+details.
+
+
+Platform data support
+---------------------
+
+The driver supports standard PMBus driver platform data.
+
+
+Sysfs entries
+-------------
+
+The following attributes are supported. Limits are read-write; all other
+attributes are read-only.
+
+in[1-4]_label		"vout[1-4]"
+in[1-4]_input		Measured voltage. From READ_VOUT register.
+in[1-4]_min		Minumum Voltage. From VOUT_UV_WARN_LIMIT register.
+in[1-4]_max		Maximum voltage. From VOUT_OV_WARN_LIMIT register.
+in[1-4]_lcrit		Critical minumum Voltage. VOUT_UV_FAULT_LIMIT register.
+in[1-4]_crit		Critical maximum voltage. From VOUT_OV_FAULT_LIMIT register.
+in[1-4]_min_alarm	Voltage low alarm. From VOLTAGE_UV_WARNING status.
+in[1-4]_max_alarm	Voltage high alarm. From VOLTAGE_OV_WARNING status.
+in[1-4]_lcrit_alarm	Voltage critical low alarm. From VOLTAGE_UV_FAULT status.
+in[1-4]_crit_alarm	Voltage critical high alarm. From VOLTAGE_OV_FAULT status.
+
+temp1_input		Measured temperature. From READ_TEMPERATURE_1 register.
+temp1_max		Maximum temperature. From OT_WARN_LIMIT register.
+temp1_crit		Critical high temperature. From OT_FAULT_LIMIT register.
+temp1_max_alarm		Chip temperature high alarm. Set by comparing
+			READ_TEMPERATURE_1 with OT_WARN_LIMIT if TEMP_OT_WARNING
+			status is set.
+temp1_crit_alarm	Chip temperature critical high alarm. Set by comparing
+			READ_TEMPERATURE_1 with OT_FAULT_LIMIT if TEMP_OT_FAULT
+			status is set.
