[U-Boot] [PATCH] arm: mxs: Increase VDDD voltage to match specification

[sbabic at denx.de]

> According to IMX28CEC rev. 4, 10/2018, Table 15. Recommended Operating
> Conditions, page 16, the VDDD should be set to 1.55V when the CPU is
> operating at 454MHz. This is the case in U-Boot, hence increase the
> VDDD voltage. This fixes instability when performing TFTP transfers.
> Increase the brownout threshold to 1.4V. The documentation recommends
> 1.45V setting for the brownout, however, this triggers failure during
> power block init, so keep the brownout slightly lower.
