log2(1) is 0 and log2(0) is -1. If we have the int64_t 0xffffffff then
log2(0xffffffff >> 31) = log2(0x1) = 0, so the current reduction code
would not shift. That's a bad idea, though, since 0xffffffff when
interpreted as an int32_t would become a negative number.
We need to always shift one more than the current code does to get a
safe reduction. This also means we can get rid of another compare/branch
since -1 is the smallest result log2() can return, so the shift can no
longer go negative now.

A UPD HybridStorageMode allows a platform to dynamically configure the
PCIe strap configuration required if an Optane device is connected.
The strap configuration is done by HECI commands between FSP and CSE to
override the default PCIe strap value, and the updated strap value is
stored in SPI RW data to be used on the next boot.
CSE Lite supports the strap override when running on CSE RW partition,
while CSE RO partition does not support it because CSE RO is not allowed
to access SPI RW data. The strap override failure on CSE RO causes FSP
not initializing PCH Clkreq and PCIe port mapping and this results NVMe
and Optane initialization failure.
By disabling HybridStorageMode in case of CSE RO boot, NVMe detection is
done by the default PCIe configuration and Optane is detected as a
single NVMe storage device on CSE RO boot in recovery mode. Both NVMe
and Optane devices detection as well as OS installation to these storage
devices are verified on CSE RO boot in recovery mode.

And really the sender of the interrupts should be conforming to the
the eSPI spec. As such inverting any signals should not be necessary,
but this register in the chipset allows for fixing up those misbehaviors.
