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.
