usb: typec: tcpm: set SRC_SEND_CAPABILITIES timeout to PD_T_SENDER_RESPONSE 

stable inclusion
from stable-v6.6.76
commit 76bae35d44f325e17f55d1a099703040ddc1dc47
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/IBW08Q

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=76bae35d44f325e17f55d1a099703040ddc1dc47



--------------------------------

commit 2eb3da037c2c20fa30bc502bc092479b2a1aaae2 upstream.

As PD2.0 spec ("8.3.3.2.3 PE_SRC_Send_Capabilities state"), after the
Source receives the GoodCRC Message from the Sink in response to the
Source_Capabilities message, it should start the SenderResponseTimer,
after the timer times out, the state machine transitions to the
HARD_RESET state.
