serial: s5p: Use livetree API to get "id" property

Browse source 
Use dev_read_u8_default() instead of fdtdec_get_int() to read the "id"
property from device tree, as suggested in [1]. dev_* API is already
used in this driver, so there is no reason to stick to fdtdec_* API.
This also fixes checkpatch warning:

    WARNING: Use the livetree API (dev_read_...)
