[U-Boot] [PATCH v4 35/35] ARM: i.MX6: sabresd: Cleanup board code

[Jagan Teki <jagan@openedev.com>]

From: Jagan Teki <jagan@amarulasolutions.com>

- Give proper tab alignment for display_info_t structure
- Add tab spaces UART_PAD_CTRL and SPI_PAD_CTRL
- Give proper alignment of reg init values on setup_display
- Add space and newline on board_init_f
