cores/cpu: Add riscv*-unknown-linux-gnu triple, fix riscv-linux-gnu
...
Add riscv*-unknown-linux-gnu to known triples, and fix the existing
riscv-linux-gnu by removing the incorrect -gcc suffix from the
triple.

software: Use -fno-stack-protector
...
This allows riscv*-gnu-linux toolchains to be used to build LiteX
software. Without this, references to undefined stack guard symbols
get generated and linking fails.

RFC: json2dts: set CPU clock-frequency and SoC bus-frequency
...
FIXME: timebase-frequency isn't to be used as the raw CPU clock, so
on vexriscv we might want to re-evaluate also setting *that* to the
`CONFIG_CLOCK_FREQUENCY`. Decide whether to keep the SoC's
`bus-frequency` cell, or whether to go with the CPU's `clock-frequency`
only.

add memory regions to soc.svd
...
svd2rust does not recognize memory regions, but we'd like to
make an access crate for Rust that does.
This patch adds memory regions to soc.svd using the "vendorExtensions"
tag, as specified in https://www.keil.com/pack/doc/cmsis/SVD/html/svd_Format_pg.html
The vendorExtensions is added as a block after the Peripherals level, and has a format
like this:
```xml
<memoryRegion>
<name>SRAM</name>
<baseAddress>0x10000000</baseAddress>
<size>0x00020000</size>
</memoryRegion>
<memoryRegion>
<name>VEXRISCV_DEBUG</name>
<baseAddress>0xEFFF0000</baseAddress>
<size>0x00000100</size>
</memoryRegion>
<memoryRegion>
<name>CSR</name>
<baseAddress>0xF0000000</baseAddress>
<size>0x00040000</size>
</memoryRegion>

liblitesdcard/sdcard.c: ensure effective sdcard clock is <= requested
...
With the way the clock divider is currently calculated, it is
possible for the effective sdcard clock to end up *higher* than
the requested `clk_freq` value.
Calculate the divider starting with the `CONFIG_CLOCK_FREQUENCY/clk_freq`
ratio which is then rounded up to the nearest power-of-two, ensuring
that the resulting, effective clock frequency is <= to the requested
frequency.
