mvebu: remove patch that was applied into linux stable

The patch
  PCI: aardvark: Don't touch PCIe registers if no card connected
was applied into Linux stable version 5.4.163.

Remove it from patches-5.4.

(It applied even though it was applied already, resulting in repeated
 code.)

Fixes: 14940aee45 ("kernel: bump 5.4 to 5.4.163")

-When there is no PCIe card connected and advk_pcie_rd_conf() or
-advk_pcie_wr_conf() is called for PCI bus which doesn't belong to emulated
-root bridge, the aardvark driver throws the following error message:
-
-  advk-pcie d0070000.pcie: config read/write timed out
-
-Obviously accessing PCIe registers of disconnected card is not possible.
-
-Extend check in advk_pcie_valid_device() function for validating
-availability of PCIe bus. If PCIe link is down, then the device is marked
-as Not Found and the driver does not try to access these registers.
-
-This is just an optimization to prevent accessing PCIe registers when card
-is disconnected. Trying to access PCIe registers of disconnected card does
-not cause any crash, kernel just needs to wait for a timeout. So if card
-disappear immediately after checking for PCIe link (before accessing PCIe
-registers), it does not cause any problems.
