mxs: Rename CONFIG_SPL_MX28_PSWITCH_WAIT to CONFIG_SPL_MXS_PSWITCH_WAIT

The power switch option is compatible with i.MX23 and i.MX28 so the configration option needs to reflect it. We choose 'CONFIG_SPL_MXS_PSWITCH_WAIT' for the option name.

1.8.1

Add a comment about the tRAS lockout setting of HW_DRAM_CTL08 to enable the 'Fast Auto Pre-Charge' found in the memory chip. The setting is applied after memory initialization and it is worth document it.

Dear Otavio Salvador,

Please read [1] too, I'm completely lost in the flurry of patches. I just can't figure out anymore what's going on. I don't know what patches to review, in what order and what patches are obsolete and what are not.

Moreover, it's generally better to use "Cc:" in the patches. Also, if you want my threading to work well so I want be lost, Cc me on the whole series.
