Add missing terminators to the arrays of IRQ, DMA, and address space
structure records in the AM35xx UART4 hwmod data. Without these
terminators, the following warnings appear on boot:
omap_uart.3: failed to claim resource 58
omap_device: omap_uart: build failed (-16)
WARNING: at /home/paul/linux/arch/arm/mach-omap2/serial.c:375 omap_serial_init_port+0x198/0x284()
Could not build omap_device for omap_uart: uart4.
Also, AM35xx uart4_fck has an incorrect parent clock pointer. Fix it
and clean up a whitespace issue.
Fix some incorrectly-named macros related to AM35xx UART4.
