ARMv7 TLB: Fixed TTBR0 and Table Descriptors to allow caching

The TTBR0 register and Table Descriptors of the ARMv7 TLB weren't being
properly set to allow for the configuration specified caching modes to
be active over DRAM. This commit fixes those issues.

ARM: cpu: Add ARMv7 barrier operations support

This enables ARMv7 barrier operations support when
march=armv7-a is enabled.

Using CP15 barriers causes U-Boot bootm command crash when
transferring control to the loaded image on Renesas R8A7794 Cortex A7 CPU.
Using ARMv7 barrier operations instead of the deprecated CP15 barriers
helps to avoid these issues.

Armv8: Initializing CNTVOFF_EL2

Linux-arm64 require that CNTVOFF_EL2 should be programmed with
a consistent value on all cpus. Initializing CNTVOFF_EL2 at state
transition instead of start.S could prevent potential different value
on cpus if ATF exist and u-boot runs at only one cpu.

Sunxi platforms come with at least 3 TWI (I2C) controllers and some platforms

sunxi: Complete mmc pin mux for each supported platform, configured with Kconfig

Sunxi platforms have different possible mmc pin mux setups (except for mmc0),
which are different across platforms.

This lets users configure which is used through the CONFIG_MMC*_PINS Kconfig
options. This is especially relevant when a second (in addition to mmc0) port
is used and CONFIG_MMC_SUNXI_SLOT_EXTRA is enabled.

sunxi: GPIO pin mux hardware-feature-specific function index defines

Each hardware feature exposed through the GPIO pin mux is usually using the same
function index (for a given port), so there is no need to define one value per
pin: one value per hardware feature per port is sufficient, avoids duplication
and makes everything easier to understand.

sunxi: common VBUS detection logic in usbc

VBUS detection could be needed not only by the musb code (to prevent host mode),
but also by e.g. gadget drivers to start only when a cable is connected.

In addition, this allows more flexibility in vbus detection, as it could easily
be extended to other USBC indexes. Eventually, this would help making musb
support independent from a hardcoded USB controller index (0).
