    While running some tests with an Olinuxino-A13-Micro + a 7" Olimex LCD module
    I noticed that the screen flickered. This is caused by the lcd display clk
    phase reg value being set to 0, where it should be 1 in this setup.
    
    This commit adds a Kconfig option for the lcd display clk phase, so that we
    can set it per board. This defaults to 1, because looking at all the fex
    files in sunxi-boards, that is by far the most used value.
    
    This commit updated the Ippo and MSI Primo73 tablet defconfigs to override the
    default of 1 with 0, as that is the correct value for those tablets, this
    keeps the register settings the same as before this commit.
    
    The Olinuxino-A13 defconfigs are not updated, changing the register setting
    for these boards from 0 to 1, this is intentional.
