From: Guanbing Huang <albanhuang@tencent.com>

The 16550a serial port based on the ACPI table requires obtaining the
reg-shift attribute. In the ACPI scenario, If the reg-shift property
is not configured like in DTS, the 16550a serial driver cannot read or
write controller registers properly during initialization.

To address the issue of configuring the reg-shift property, the 
__uart_read_properties() universal interface is called to implement it.
Adaptation of PNP devices is done in the __uart_read_properties() function.

Guanbing Huang (3):
  PNP: Add dev_is_pnp() macro
  serial: port: Add support of PNP IRQ to __uart_read_properties()
  serial: 8250_pnp: Support configurable reg shift property
