usb: typec: intel_pmc_mux: Do not configure SBU and HSL Orientation in Alternate modes
According to the PMC Type C Subsystem (TCSS) Mux programming guide rev
0.7, bits 4 and 5 are reserved in Alternate modes.
SBU Orientation and HSL Orientation needs to be configured only during
initial cable detection in USB connect flow based on device property of
"sbu-orientation" and "hsl-orientation".
Configuring these reserved bits in the Alternate modes may result in delay
in display link training or some unexpected behaviour.
So do not configure them while issuing Alternate Mode requests.
Fixes: ff4a30d5e243 ("usb: typec: mux: intel_pmc_mux: Support for static SBU/HSL orientation")
