d76867efeb net: txgbe: use pci_dev_id() helper 
PCI core API pci_dev_id() can be used to get the BDF number for a PCI
device. We don't need to compose it manually. Use pci_dev_id() to
simplify the code a little bit.

This reverts commit e30cef001d.
commit 99f4570cfb ("clkdev: Update clkdev id usage to allow
for longer names") can fix clk_name exceed MAX_DEV_ID limits,
so this commit is meaningless.

This reverts commit c644920ce9.

c644920ce9 net: txgbe: fix i2c dev name cannot match clkdev 
txgbe clkdev shortened clk_name, so i2c_dev info_name
also need to shorten. Otherwise, i2c_dev cannot initialize

e30cef001d net: txgbe: fix clk_name exceed MAX_DEV_ID limits 
txgbe register clk which name is i2c_designware.pci_dev_id(),
clk_name will be stored in clk_lookup_alloc. If PCIe bus number
is larger than 0x39, clk_name size will be larger than 20 bytes.
It exceeds clk_lookup_alloc MAX_DEV_ID limits. So the driver
shortened clk_name.

0e71862a20 net: txgbe: fix to clear interrupt status after handling IRQ 
GPIO EOI is not set to clear interrupt status after handling the
interrupt. It should be done in irq_chip->irq_ack, but this function
is not called in handle_nested_irq(). So executing function
txgbe_gpio_irq_ack() manually in txgbe_gpio_irq_handler().

b4a2496c17 net: txgbe: fix GPIO interrupt blocking 
The register of GPIO interrupt status is masked before MAC IRQ
is enabled. This is because of hardware deficiency. So manually
clear the interrupt status before using them. Otherwise, GPIO
interrupts will never be reported again. There is a workaround for
clearing interrupts to set GPIO EOI in txgbe_up_complete().

aefd013624 net: txgbe: use irq_domain for interrupt controller 
In the current interrupt controller, the MAC interrupt acts as the
parent interrupt in the GPIO IRQ chip. But when the number of Rx/Tx
ring changes, the PCI IRQ vector needs to be reallocated. Then this
interrupt controller would be corrupted. So use irq_domain structure
to avoid the above problem.
