serial: esp32_uart: Use device_get_match_data()

Use preferred device_get_match_data() instead of of_match_device() to
get the driver match data. With this, adjust the includes to explicitly
include the correct headers.

Error checking for matching was not necessary as matching is always
successful if we're already in probe and the match tables always have data
pointers.
