serial: 8250_pci: fix mode after S3/S4 resume for F81504/508/512
Fix RS232/485 mode incorrect setting after S3/S4 resume for F81504/508/512
We had add RS232/485 RTS control with fecf27a373f5. But when it
resume from S3/S4, the mode register 0x40 + 0x08 * idx + 7 will
rewrite to 0x01 (RS232 mode).
This patch will modify 2 sections.
One is pci_fintek_init(), if it called when first init, it will
write mode register with 0x01. If it called from S3/S4 resume,
it's will get the relative port data and pass it to
pci_fintek_rs485_config() with NULL rs485 parameter.
The another modification is in pci_fintek_rs485_config(). It'll
re-apply old configuration when the parameter rs485 is NULL.
