We don't have a reset method on any RISC-V board yet. Instead of
adding the same 'unsupported' message for each CPU variant it might
make more sense to add a generic do_reset function for all CPU
variants to lib/, similar to the one for ARM (arch/arm/lib/reset.c).

This adds QEMU RISC-V 'virt' board target support, with the hope of
helping people easily test U-Boot on RISC-V.
The QEMU virt machine models a generic RISC-V virtual machine with
support for the VirtIO standard networking and block storage devices.
It has CLINT, PLIC, 16550A UART devices in addition to VirtIO and
it also uses device-tree to pass configuration information to guest
software. It implements RISC-V privileged architecture spec v1.10.
Both 32-bit and 64-bit builds are supported. Support is pretty much
preliminary, only booting to U-Boot shell with the UART driver on
a single core. Booting Linux is not supported yet.

At present the compiler flag against which architecture and abi
variant the riscv image is built for is not explicitly indicated
which means the default compiler configuration is used. But this
does not work if we want to build a different target (eg: 32-bit
riscv images using a toolchain configured for 64-bit riscv).
Fix this by explicitly passing -march and -mabi to the compiler.
Since generically we don't use floating point in U-Boot, specify
the RV[32|64]IMA ISA and software floating ABI.
This also fix some alignment coding style issues.

The first argument of Linux kernel is the risc-v core hart id,

While we are here, this also changes the Linux kernel entry
parameters' type to support both 32-bit and 64-bit.
Note the hart id is hardcoded to zero for now, and we should
change to fill in it with the value read from mhartid CSR of

It is good practice to make the setting of gpio-pinctrls explicitly in the
devicetree, and in this case even necessary.
Rockchip boards start with iomux settings set to gpio for most pins and
while the linux pinctrl driver also implicitly sets the gpio function if
a pin is requested as gpio that is not necessarily true for other drivers.
The issue in question stems from uboot, where the sdmmc_pwr pin is set
to function 1 (sdmmc-power) by the bootrom when reading the 1st-stage
loader. The regulator controlled by the pin is active-low though, so
when the dwmmc hw-block sets its enabled bit, it actually disables the
regulator. By changing the pin back to gpio we fix that behaviour.
