they are not mentioned in the Kconfig help when the code was added.

commit 101bd907b4 ("misc: rtsx: judge ASPM Mode to set PETXCFG Reg")
some readers no longer force #CLKREQ to low
when the system need to enter ASPM.
But some platform maybe not implement complete ASPM?
it causes some platforms can not boot
Like in the past only the platform support L1ss we release the #CLKREQ.
Move the judgment (L1ss) to probe,
we think read config space one time when the driver start is enough

"priv->ext_config_dev_aspm" was never set to a non-zero value. Therefore,
alcor_pci_aspm_ctrl(priv, 1) did nothing, and alcor_pci_aspm_ctrl(priv, 0)
always disabled ASPM in the device and the upstream bridge.
The driver disabled ASPM in alcor_pci_probe() and alcor_resume(), so it's
possible the device doesn't work well when ASPM is enabled.
Remove all the ASPM-related code and replace the alcor_pci_aspm_ctrl(0)
calls with pci_disable_link_state(pdev, PCIE_LINK_STATE_L0S |
PCIE_LINK_STATE_L1), which asks the PCI core to disable ASPM.

uses "rtd3_work" and "idle_work" to manage it's own runtime PM state
machine.
When its child device, rtsx_pci_sdmmc, uses runtime PM refcount
correctly, all the additional works can be managed by generic runtime PM
helpers.
So consolidate "idle_work" and "rtd3_work" into generic runtime idle
callback and runtime suspend callback, respectively.

There is an issue with the ASPM(optional) capability checking function.
A device might be attached to root complex directly, in this case,
bus->self(bridge) will be NULL, thus priv->parent_pdev is NULL.
Since alcor_pci_init_check_aspm(priv->parent_pdev) checks the PCI link's
ASPM capability and populate parent_cap_off, which will be used later by
alcor_pci_aspm_ctrl() to dynamically turn on/off device, what we can do
here is to avoid checking the capability if we are on the root complex.
This will make pdev_cap_off 0 and alcor_pci_aspm_ctrl() will simply
return when bring called, effectively disable ASPM for the device.

changed rtsx_pci_disable_aspm() to rtsx_disable_aspm()
do not access ASPM configuration directly
changed pcie_capability_write_word() to _clear_and_set_word()
make sure only change PCI_EXP_LNKCTL bit8
make sure ASPM disable after extra_init_hw()
