PCI/ASPM: Consolidate link state defines
The linux/pci.h and aspm.c files define their own sets of link state
related defines which are almost the same.
Consolidate the use of defines into those defined by linux/pci.h and expand
PCIE_LINK_STATE_L0S to match earlier ASPM_STATE_L0S that includes both
upstream and downstream bits. Rename also the defines that are internal to
aspm.c to start with PCIE_LINK_STATE for consistency.
While the PCIE_LINK_STATE_L0S BIT(0) -> (BIT(0) | BIT(1)) transformation is
not 1:1, in practice aspm.c already used ASPM_STATE_L0S that has both bits
enabled except during mapping.
While at it, place the PCIE_LINK_STATE_CLKPM define last to have more
logical grouping.
Use static_assert() to ensure PCIE_LINK_STATE_L0S is strictly equal to the
combination of PCIE_LINK_STATE_L0S_UP/DW.
