regulator: fixed: reject incompatible platform devices
The fixed regulator driver expects non-DT platform devices to provide
their configuration through platform_data as a struct fixed_voltage_config.
An explicitly bound driver can bypass the normal platform device/driver
matching and attach the fixed regulator driver to an unrelated platform
device. This causes the driver's platform_data to be interpreted as a
struct fixed_voltage_config even though it contains data for a different
device.
Reject non-DT platform devices whose name does not match the fixed
regulator driver before accessing their platform data.
Fixes: 4b74ff651249 ("regulator: add support for fixed regulators.")
