When using a linker script which does not provide a .time_critical.
section that is marked "ax" and wrongly define
PICO_INT64_OPS_IN_RAM=1 this would generate a malformed
executable with strange runtime bugs in the worst case.
The mask passed in shouldn't already be shifted by ADC_CS_RROBIN_LSB
(16) otherwise the shift in the call to hw_write_masked() would shift
all of the bits off the end of the mask, hence we should be asserting
not against ADC_CS_RROBIN_BITS (0x1f0000) but against the number of ADC
channels available.
Fixes the following compiler warning
```
.../vendor/pico-sdk/src/rp2_common/pico_runtime/runtime.c: In function 'panic':
.../pico-sdk/src/rp2_common/pico_runtime/runtime.c:284:1: warning: 'noreturn' function does return

```
* fix __force_inline for different GCC versions in cpp mode (the affected versions are different from c mode), and build kitchsink.c as a cpp file too for testing
* silly bug in host platform.h
* Platform updates
- Add PICO_RP2040=1 to rp2040 builds
- Add new PICO_RP2040_B0/1/2_SUPPORTED macros and retailer chip specific code to use
- Add doxygen to platform.h
- Make pico.h includable from assembly (because header order is important and tricky) - split out platform_asm.h
- Switch to using PICO_RP2040_B0_SUPPORTED in board headers
mutex_t and mutex_ are reverted to non recursive versions (pre SDK1.2.0) and new recursive_mutex_t and recursive_mutex_ functions have been added
PICO_MUTEX_ENABLE_SDK120_COMPATIBILITY flag has been added to allow old SDK1.2.0 compatibility (i.e. mutex_t can be used recursively or not) but this is slower (and is will be removed in a future version)
add watchdog_enable_caused_reboot. Note there is a small backwards incompatibility in so far as watchdog_enable sets scratch[4] to a magic value not 0 now, however this behavior was not documented before.
* add stdio_usb_connected() method
* add PICO_STDIO_USB_CONNECT_WAIT_TIMEOUT_MS to allow waiting for CDC connection during init(*
* add puts_raw and putchar_raw to skip any CR/LF translation
Fixes build when pico_stdlib isn't included in the target libraries:
pico-sdk/src/rp2_common/pico_divider/divider.S:8:10: fatal error: hardware/divider_helper.S: No such file or directory
Also fixes the same error in pico_double, though I'm not sure how/why:
pico-sdk/src/rp2_common/pico_double/double_aeabi.S:9:10: fatal error: hardware/divider_helper.S: No such file or directory
