This patch is used to support DBD owner fuse changed to S400 only.
The XRDC PDAC2 for LPAV pbridge5 and MSC1/2/3 for GPIO and LPAV are not
configured by S400 default setting. So these PDAC and MSC are invalid,
only DBD owner can access the corresponding resources.
We have to configure necessary PDAC and MSC for SPL before DDR
initialization.

To fit the DBD_EN fused part, we re-design the TRDC and XRDC assignment.
M33 will be the TRDC owner and needs to configure TRDC. A35 is the
XRDC owner, ATF will configure XRDC.
The handshake between U-boot and M33 image is used to sync TRDC and
XRDC configuration completion. Once the handshake is done, A35 and M33
can access the allowed resources in others domain.
The handshake is needed when M33 is booted or DBD_EN fused, because both
cases will enable the TRDC. If handshake is timeout, the boot will hang.
We use SIM GPR0 to pass the info from SPL to u-boot, because before the
handshake, u-boot can't access SEC SIM and FSB.

When M33 is LPAV owner in dual boot, DDR, PCC5, CGC2 won't be reset
during APD reset. So no need to init DDR again after reboot, but need to
reconfigure the PLL4 PFD/PFDDIV/LPAV NIC etc, because kernel may
change or disable some of them.

The DDRLOCKED bit in CGC2 DDRCLK will auto lock up and down by HW
according to DDR DIV updating or DDR CLK halt status change. So DDR
PCC disable/enable will trigger the lock up/down flow. We
need wait until unlock to ensure clock is ready.
And before configuring the DDRCLK DIV, we need polling the DDRLOCKED
until it is unlocked. Otherwise writing ti DIV bits will not set.
