The way patches are organized, it breaks git bisect-ability
because PATCH2 depends on PATCH3. Also, PATCH3 should
be squashed into PATCH7.

Based on dependency, here's better ordering of patches:
PATCH1) riscv: Add DMA 64-bit address support
PATCH2) net: macb: Add DMA 64-bit address support for macb
PATCH3) net: macb: Add phy address to read it from device tree
PATCH4) clk: Add Microchip PolarFire SoC clock driver
(Note: PATCH4 also include "dt-bindings: clock: Add indexes for reset signals")
PATCH5) riscv: dts: Add device tree for Microchip Icicle Kit
PATCH6) riscv: Add Microchip MPFS Icicle Kit support
PATCH7) doc: board: Add Microchip MPFS Icicle Kit doc
