From: Pali Rohár <pali@kernel.org>

Define SPEED_GEN_* macros with correct PCIE_GEN_SEL_SHIFT.

Simplify macro for setting root complex mode (use BIT instead of
MSK + SHIFT).

Rename PCIE_MSG_PM_PME_MASK to PCIE_ISR0_MSG_PM_PME to match existing
naming convention, rename PCIE_ISR0_MSI_INT_PENDING to PCIE_ISR0_MSI_INT
as it is used for both interrupt mask and pending bit.
