dt-bindings: serial: 8250: add aspeed, lpc-io-reg and aspeed, lpc-interrupts

Browse source 
These correspond to the existing lpc_address, sirq, and sirq_polarity
sysfs attributes; the second element of aspeed,lpc-interrupts provides
a replacement for the deprecated aspeed,sirq-polarity-sense property.
