[U-Boot] [PATCH 06/10] exynos: Enable PSHOLD in SPL

[Lukasz Majewski]

Hi Simon,

> There is quite a tight deadline in enabling PSHOLD, less than a
> second. In some cases (e.g. with USB download), U-Boot takes longer
> than that to load, so the board powers off before U-Boot starts.
> 
> Add a call in SPL to enable PSHOLD.
