[v4,0/8] Add Toshiba Visconti ARM64 Platform support

Message

Visconti is a series of Toshiba's SoCs targeting image processing
applications[0]. These set of patches adds support for Visconti5 a Arm
v8 based SoC.

The series add minimal support for the Visconti5 SoC and the TMPV7708 RM
main board. Peripherals such as UART, SPI, I2c and timer use Arm's
IP and work with the existing kernel drivers in the tree. The series
includes a pinctrl driver to select appropriate functions on the pins.

NOTE: Because Visconti5 does not have PSCI, it uses spin-table with enable-method.
      And this patch series does not include a clock framework, so it is a
      device-tree file that uses clocks with fixed-clock. This will be replaced by
      the clock driver in the future.
