Configure the SiFive Freedom SoC to bind to the I2C Peripheral.
Note: The FE310-G000 used on the HiFive 1 does not posess the I2C
peripheral. However, the FE310 platform can have an I2C device memory
mapped in the location described in riscv32-fe310.dtsi.

This board is unmaintained and unsupported. It is not known to work and
has lots of conditional code across the tree that makes code
unmaintainable.

Add a level 2 interrupt controller for the RV32M1 SoC. This uses the
INTMUX peripheral.
As a first customer, convert the timer driver over to using this,
adding nodes for the LPTMR peripherals. This lets users select the
timer instance they want to use, and what intmux channel they want to
route its interrupt to, using DT overlays.

Add a Peripheral Clock Controller (PCC) driver. This gates and ungates
clocks to various peripherals on the SoC.

The OpenISA RV32M1 SoC has four CPU cores. Two of these are RISC-V
32-bit cores, which are named "RI5CY" and "ZERO-RISCY". (The other two
cores are ARM Cortex-M0+ and -M4.) This patch adds basic SoC
enablement for the RISC-V cores:
- basic dtsi, to be extended as additional drivers are added
- SoC definition in soc/riscv32/openisa_rv32m1 for RI5CY / ZERO-RISCY
- system timer driver for RI5CY, based on LPTMR0 peripheral
The timer driver will be generalized a bit soon once proper
multi-level interrupt support is available.
Emphasis is on supporting the RI5CY core as the more capable of the
two; the ZERO-RISCY SoC definitions are a good starting point, but
additional work setting up a dtsi and initial drivers is needed to
support that core.

dtc produces the following warning:
Warning (simple_bus_reg): /soc/itim@8000000: simple-bus unit address
format error, expected "0"
We had the wrong unit address in the dtsi file, should be 0.

Add #pwm-cells to the sifive PWM binding and dts files. This is to
support have a pwms clients work properly.

Add minimal DTS support for the m2gl025_miv. The dts just has the core,
SoC, PLIC, and UART described. We still get memory related info from
Kconfig.

Add the missing bits to the yaml, dts, and Kconfig to enable GPIO pin

Add the needed bits to get device tree support for the GPIO controller
on the Zedboard-Pulpino. This will allow us to move LED & button info
into the board.dts.

Add simple device tree support for the Pulpino SoC and Zedboard-Pulpino
board port. This gets the UART info from device tree instead of soc.h
