This patch fixes a possible interrupt storm condition by
the USB wake IRQ, which can cause a dog timeout crash.
The USB wake IRQ detects USB bus suspend on USB D+ line.
This can be done by a rising edge triggered interrupt,
rather than level triggered interrupt.

Currently we just check the most significant two bits of a dword
in the ringbuffer or IB are set to decide if the data is a type3

that the top two bits are often set in nominal data. Enhance
the type3 packet check to verify that various reserved bits in
the dword are 0 as expected.

Change the configuration of PM8921 regulators SMPS 7 and LDO 27
so that requests sent to the RPM for these regulators have pd=0
(i.e. pull-down disabled). This modification reduces leakage
current that is seen during XO shutdown when S7 and L27 are
disabled but S3 is kept on. The outputs of S3 and L27 are wired
together so the S3 output voltage is continuously dropped across
the L27 pull-down resistor if it is enabled. S7 is the parent
supply of L27 so the same problem is seen if its pull-down
resistor is enabled.
