Ye Li 06fc74102a mx7ulp_evk: Update DDR freq to 352.8Mhz for ULP B0
On i.MX7ULP B0, the DDR clock target is increased from 320Mhz to 380Mhz.
We update DDR clock relevant settings to approach the target. But since the
limitation on LCDIF pix clock for HDMI output
(refer "mx7ulp_evk: Change APLL and its PFD0 frequencies"), we set DDR
clock to 352.8Mhz (25.2Mhz * 14) by using the clock path:

	APLL PFD0 -> DDR CLK -> NIC0 -> NIC1 -> LCDIF clock

To reduce the impact to entire system, the NIC0_DIV and NIC1_DIV are kept,
so the divider 14 is calculated as:
	14 = (NIC0_DIV + 1) * (NIC1_DIV + 1) * (LCDIF_PCC_DIV + 1)

	NIC0_DIV:      1
	NIC1_DIV:      0
	LCDIF_PCC_DIV: 6

APLL and APLL PFD0 settings:

	PFD0 FRAC:  27
	APLL MULT:  22
	APLL NUM:   1
	APLL DENOM: 20

This patch applies the new settings for both DCD and plugin.
There is no DDR script change on this new frequency.
Overnight memtester is passed.
