Revert this commit as it wasn't reliably work as expected by massive test.
The problem is clear now that cxpl_debug_info from DWC core is missing
rdlh_link_up. So reading PCIE_PORT_DEBUG1 and check smlh_link_up isn't enough.
Quoted from DWC databook, section 8.2.3 AXI Bridge Initialization, Clocking and Reset:
"In RC Mode, your AXI application must not generate any MEM or I/O
requests, until the host software has enabled the Memory Space Enable
(MSE), and IO Space Enable (ISE) bits respectively. Your RC application
should not generate CFG requests until it has confirmed that the link is
up by sampling the smlh_link_up and rdlh_link_up outputs."
The problem was introduced by commit 1 and fixed by commit 2 but not to
the end. And finally commit 3 rename the register but not fix anything.
It was broken from the first time. Any dwc controller should be use the
buggy default method to check link up state. So revert this commit to use
our own link_up hook. The timing is drving smlh_link_up->L0->rdlh_link_up->
FC init(a fixed delay) from IC simulation. So the origin code is working. What
we were trying to fix is the link suddenly broke after link was already up.
However, it could happen anytime, even just after passing dw_pcie_link_up
check. So it's function drivers responsibility to check 0xffffffff return value
to be aware of the link broken state and do a proper retry or recovery.

sub-driver doesn't override")
[2]. commit 01c076732e ("PCI: designware: Check LTSSM training bit
before deciding link is up")

definitions")
This reverts commit a095b98601.

When s otp and ns otp are accessed simultaneously,
do not close the common clk to avoid reading failures.

SPI transmission exception is often caused by an abnormality in the
IRQ subsystem in the environment, so an attempt is made to switch
to the poll transmission scheme in order to expect the SPI module
to continue working.

Configure "rockchip,txdone-irq" property in DT indicates that the
controller can trigger the TX_DONE interrupt. This feature begin
support from RV1103B and RK3506 SoCs with Rockchip mailbox v2 IP.
If the mailbox client wants to use its own ACK to check TX_DONE,
the "rockchip,txdone-ack" property also gets reday for it in
this patch.

This adds a standalone driver to support PCIe hotplug functionality
merely based on a GPIO indicating the status of a downstream device
connectivity. It looks for "hotplug-gpios" property in the corresponding
device node to get the GPIO information.
It also provides a mechanism for platform drivers of the controllers
to register ops to perform any platform specific operations while
enabling/disabling the slots.
