armv7/exynos5420: Revise SPI open/close/reset procedure.

The original Exynos SPI open/close procedure was copied from U-Boot SPL with
some assumptions that only works in SPL stage.  For example, it tries to always
work in 4-byte transmission mode with only RX data is swapped, and claims a
packet for initial address command (and with incorrect size).

This commit revises open/close and reset so only the required SPI registers are
configured.
