Please find below the possible explanation for all patches:

serial: pl01x: pass pl01x_type to set baudrate
- This patch only affect if DM is not defined.
If you are using driver model for pl011, pl011 will work without this patch.

serial: pl01x: fix pl011 baud rate configuration
- If pl011 is already configured to correct baudrate or LCR register is 
being written later.

serial: pl01x: move all line control at same place
- this patch does not affect the functionality.

serial: pl01x: disable as per type of pl01x
- pl011 might work without disabling it properly at start.
pl010 control register(disable bit) location is reserved in case of pl011.

serial: pl01x: avoid pl01x type check two times
- does not affect the functionality.
