[PATCH v2 1/2] serial: 8250: Correct Kconfig help text for blacklisted PCI devices

["Maciej W. Rozycki" <macro@orcam.me.uk>]

Correct the Kconfig help text for SERIAL_8250_LPSS, SERIAL_8250_MID and 
SERIAL_8250_PERICOM configuration options for dedicated PCI UART drivers 
that have been blacklisted in the generic PCI 8250 UART driver and as 
from commit a13e19cf3dc10 ("serial: 8250_lpss: split LPSS driver to 
separate module"), commit d9eda9bab2372 ("serial: 8250_pci: Intel MID 
UART support to its own driver"), and commit fcfd3c09f4078 ("serial: 
8250_pci: Split out Pericom driver") respectively are not handled by 
said driver anymore (rather than for extra features only, as the current 
text indicates), and therefore require the respective dedicated drivers 
to work at all.
