drivers/tty/serial/8250: Make Aspeed VUART SIRQ polarity configurable
Make the SIRQ polarity for Aspeed AST24xx/25xx VUART configurable via sysfs. This setting need to be changed on specific host platforms depending on the selected host interface (LPC / eSPI). The setting is configurable via sysfs rather than device-tree to stay in line with other related configurable settings. On AST2500 the VUART SIRQ polarity can be auto-configured by reading a bit from a configuration register, e.g. the LPC/eSPI interface configuration bit. Tested: Verified on TYAN S7106 mainboard.
