pcie: host: tegra: increase pcie linkup time

increases pcie link up time from its current 100ms
value to 350ms value because of the specific USB3.0 controller
card based on VIA chipset takes around 350ms time to linkup
with rootport. To be at par with x86 machine interms of
device enumeration, this change is required.
Also, this changes comes into picture only if there is a device
found (i.e. only if TX_RDET_STATUS is already set)
