Javier Carrasco 409c1cfb5a usb: typec: tipd: fix event checking for tps6598x
The current interrupt service routine of the tps6598x only reads the
first 64 bits of the INT_EVENT1 and INT_EVENT2 registers, which means
that any event above that range will be ignored, leaving interrupts
unattended. Moreover, those events will not be cleared, and the device
will keep the interrupt enabled.

This issue has been observed while attempting to load patches, and the
'ReadyForPatch' field (bit 81) of INT_EVENT1 was set.

Given that older versions of the tps6598x (1, 2 and 6) provide 8-byte
registers, a mechanism based on the upper byte of the version register
(0x0F) has been included. The manufacturer has confirmed [1] that this
byte is always 0 for older versions, and either 0xF7 (DH parts) or 0xF9
(DK parts) is returned in newer versions (7 and 8).

Read the complete INT_EVENT registers to handle all interrupts generated
by the device and account for the hardware version to select the
register size.
