serial: 8250: Correct Kconfig help text for blacklisted PCI devices

Browse Source 
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.
