omap1: Fix redundant UARTs pin muxing that can break other hardware support
Commit 15ac408ee5a509053a765b816e9179515329369f removed enabled_uart and OMAP_TAG_UART. This works for mach-omap2, but causes issues on mach-omap1 for some boards as the mach-omap1 serial.c was muxing pins based on the enabled_uart flag for 15xx. Fix this by muxing pins in board-*.c files for the 15xx boards for the uart ports that had enabled_uart flag set before the commit above. Tested on Amsdtrad Delta only. Note that in the future we should add support for powering down the uarts with a timer like mach-omap2/serial.c does. Otherwise the enabled uarts will be blocking retention-while-idle.
