usb: typec: tcpm: delay SNK_TRY_WAIT_DEBOUNCE to SRC_TRYWAIT transition
This patch fixes Type-C Compliance Test TD 4.7.6 - Try.SNK DRP Connect
SNKAS.
The compliance tester moves into SNK_UNATTACHED during toggling and
expects the PUT to apply Rp after tPDDebounce of detection. If the port
is in SNK_TRY_WAIT_DEBOUNCE, it will move into SRC_TRYWAIT immediately
and apply Rp. This violates TD 4.7.5.V.3, where the tester confirms that
the PUT attaches Rp after the transitions to Unattached.SNK for
tPDDebounce.
Change the tcpm_set_state delay between SNK_TRY_WAIT_DEBOUNCE and
SRC_TRYWAIT to tPDDebounce.
