8250: microchip: pci1xxxx: Add Syslock support for reading UART system registers
Different Host drivers can attempt to access system registers
simultaneously from different memory spaces at the same time. The
syslock mechanism provides a safe option for reading UART system
registers and prevents conflicts by serializing access. Added
three padding bytes in the structure for memory alignment.
