Subject: [PATCH v6 09/14] USB: typec: Refactor tps6598x port registration
From: Abdel Alkuor <abdelalkuor@...tab.com>
tps6598x and cd321x use TPS_REG_SYSTEM_CONF to get dr/pr roles
where other similar devices don't have this register such as tps25750.
Move tps6598x port registration to its own function
Signed-off-by: Abdel Alkuor <abdelalkuor@...tab.com>

Changes in v6:
- No changes
