pci: msm: Extend sleep time when reset i2c client

For HSP link down issue on CPE platform, because CPE NTN3 pcie switch
separates pcie link between RC and EP into two pcie buses,
RC0<->USP and DSP<->EP, so we should take care of this case on pcie
link training, make code change as following:
1. do link training RC0<->USP first and then do link training for
   DSP<->EP
2. link training of DSP<->EP need more time to complete.
From test result, 100ms is not enough, 200ms is ok.
