ARM: OMAP AM35xx: clock and hwmod data: fix UART4 data

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.
