UCSI v2 specification has increased the MSG_IN and MSG_OUT size from
16 bytes to 256 bytes each for the message exchange between OPM and PPM
This makes the total buffer size increase from 48 bytes to 528 bytes.
Update the buffer size to support this increase.

While at it also update the UCSI read/request buffers to be packed.

Changes since v2:
 - Added "usb: typec: ucsi_glink: Update request/response buffers
   to be packed" patch
 - Added length checks
 - Updated version checks to use UCSI_VERSION_2_0 instead of UCSI_VERSION_2_1

Changes since v1:

 - Removed UCSI_BUF_SIZE and used the explicit v1 or v2 buffer size macros
 - Removed Qualcomm copyright
