Subject: [PATCH 4/8] usb: typec: ucsi: glink: use le32 for message data

The message structures as transferred by the PMIC_GLINK use le32 for
data encoding. Correct struct accessors to follow the lead of the main
pmic_glink.c driver.

Fixes: 62b5412b1f4a ("usb: typec: ucsi: add PMIC Glink UCSI driver")
