[PATCH] thermal/drivers/mediatek: remove redundant dev_warn in probe

[Alexandru Ardelean <alex@shruggie.ro>]

There's no need to print any extra messages in the driver if
devm_thermal_add_hwmon_sysfs() fails.
If this function has any failures, they will already be printed.

While looking inside 'drivers/thermal/mediatek/auxadc_thermal.c', the
failure will be either be one of:
  'Failed to allocate device resource data'
or
  'Failed to add hwmon sysfs attributes'

Also, the failure will be reported on the 'dev' object passed to
'devm_thermal_add_hwmon_sysfs()', so it should be clear which device this
error belongs to.
