Convert CONFIG_SYS_NS16550_MEM32 et al to Kconfig
This converts the following to Kconfig: CONFIG_SPL_NS16550_MIN_FUNCTIONS CONFIG_SYS_NS16550_MEM32 CONFIG_SYS_NS16550_PORT_MAPPED CONFIG_SYS_NS16550_REG_SIZE CONFIG_SYS_NS16550_SERIAL To do this we also introduce CONFIG_SPL_SYS_NS16550_SERIAL so that platforms can enable the legacy driver here for SPL.

Enable this option to allow device-tree control of the driver.
Normally this driver is controlled by the following options:
- CONFIG_SYS_NS16550_PORT_MAPPED - indicates that port I/O is used for
- access. If not enabled, then the UART is memory-mapped.
- CONFIG_SYS_NS16550_MEM32 - if memory-mapped, indicates that 32-bit
- access should be used (instead of 8-bit)
- CONFIG_SYS_NS16550_REG_SIZE - indicates register width and also
- endianness. If positive, big-endian access is used. If negative,
- little-endian is used.
-
It is not a good practice for a driver to be statically configured,
since it prevents the same driver being used for different types of
UARTs in a system. This option avoids this problem at the cost of a
slightly increased code size.
