Denis Efremov 688033f52d PCI: pciehp: Add pciehp_set_indicators() to set both indicators
Add pciehp_set_indicators() to set power and attention indicators with a
single register write.

This is a minor optimization because we frequently set both indicators and
this can do it with a single command.  It also reduces the number of
interfaces related to the indicators and makes them more discoverable
because callers use the PCI_EXP_SLTCTL_ATTN_IND_* and
PCI_EXP_SLTCTL_PWR_IND_* definitions directly.

[bhelgaas: extend commit log, s/PCI_EXP_SLTCTL_.*_IND_NONE/INDICATOR_NOOP/
so they don't look like things defined by the spec, add function doc, mask
commands to make it obvious we only send valid commands
(pcie_do_write_cmd() does mask it, but requires more effort to verify)]
