6e7628c8c3 PCI: microchip: Remove dev_err() when handing an error from platform_get_irq() 
There is no need to call the dev_err() function directly to print a
custom message when handling an error from either the platform_get_irq()
or platform_get_irq_byname() functions as both are going to display an
appropriate error message in case of a failure.

This change is as per suggestions from Coccinelle, e.g.,
  drivers/pci/controller/pcie-microchip-host.c:1027:2-9: line 1027 is
  redundant because platform_get_irq() already prints an error

Related commit caecb05c8000 ("PCI: Remove dev_err() when handing an
error from platform_get_irq()").

2c61f32124 PCI: microchip: Make some symbols static 
The sparse tool complains as follows:

drivers/pci/controller/pcie-microchip-host.c:304:18: warning:
 symbol 'pcie_event_to_event' was not declared. Should it be static?
drivers/pci/controller/pcie-microchip-host.c:310:18: warning:
 symbol 'sec_error_to_event' was not declared. Should it be static?
drivers/pci/controller/pcie-microchip-host.c:317:18: warning:
 symbol 'ded_error_to_event' was not declared. Should it be static?
drivers/pci/controller/pcie-microchip-host.c:324:18: warning:
 symbol 'local_status_to_event' was not declared. Should it be static?

Those symbols are not used outside of pcie-microchip-host.c, so this
commit marks them static.
