8250_men_mcb: Read num ports from register data.
The IP Core Z025 and Z057 have a register where the amount of UART ports is specified. Such register is located at offset 0x40. This patch fixes the way the UART ports is calculated by reading the actual register. Additionally a refactor was needed to achieve this so we can keep track of the UART line and its offset which also improves the remove callback.
