PCI: qcom: Use bulk reset APIs for handling resets for IP rev 2.4.0
All the resets are asserted and deasserted at the same time. So the bulk
reset APIs can be used to handle them together. This simplifies the code
a lot.
It should be noted that there were delays in-between the reset asserts and
deasserts. But going by the config used by other revisions, those delays
are not really necessary. So a single delay after all asserts and one after
deasserts is used.
The total number of resets supported is 12 but only ipq4019 is using all of
them.
