Tegra: introduce plat_enable_console()

This patch introduces the 'plat_enable_console' handler to allow
the platform to enable the right console. Tegra194 platform supports
multiple console, while all the previous platforms support only one
console.

For Tegra194 platforms, the previous bootloader checks the platform
config and sets the uart-id boot parameter, to 0xFE. On seeing this
boot parameter, the platform port uses the proper memory aperture
base address to communicate with the SPE. This functionality is
currently protected by a platform macro, ENABLE_CONSOLE_SPE.

This patch adds support to save the system suspend entry and exit

The Tegra194 platform handler sets the system suspend entry marker
before entering SC7 state and the trampoline flips the state back to
system resume, on exiting SC7.

Tegra194: program stream ids for XUSB

T194 XUSB has support for XUSB virtualization. It will have one
physical function (PF) and four Virtual function (VF)

There were below two SIDs for XUSB until T186.
1) #define TEGRA_SID_XUSB_HOST 0x1bU
2) #define TEGRA_SID_XUSB_DEV 0x1cU

We have below four new SIDs added for VF(s)
3) #define TEGRA_SID_XUSB_VF0 0x5dU
4) #define TEGRA_SID_XUSB_VF1 0x5eU
5) #define TEGRA_SID_XUSB_VF2 0x5fU
6) #define TEGRA_SID_XUSB_VF3 0x60U

When virtualization is enabled then we have to disable SID override
and program above SIDs in below newly added SID registers in XUSB
PADCTL MMIO space. These registers are TZ protected and so need to
be done in ATF.
a) #define XUSB_PADCTL_HOST_AXI_STREAMID_PF_0 (0x136cU)
b) #define XUSB_PADCTL_DEV_AXI_STREAMID_PF_0 (0x139cU)
c) #define XUSB_PADCTL_HOST_AXI_STREAMID_VF_0 (0x1370U)
d) #define XUSB_PADCTL_HOST_AXI_STREAMID_VF_1 (0x1374U)
e) #define XUSB_PADCTL_HOST_AXI_STREAMID_VF_2 (0x1378U)
f) #define XUSB_PADCTL_HOST_AXI_STREAMID_VF_3 (0x137cU)

This change disables SID override and programs XUSB SIDs in
above registers to support both virtualization and non-virtualization.
