Remove references to hardware_rtc for rp2350
Reimplement time functioniality
Use hardware_powman instead
Define PICO_PLATFORM for RPI_PICO
move PICO_TINYUSB_PATH until PICO_PLATFORM is defined
PICO_TINYUSB_PATH has to be defined before calling pico_sdk_init
Make sure powerman timer is using xosc
ports/rp2: Updates for powman changes.
Probably another change coming to remove powman and use the new aon
    timer that supports both rp2040 and rp2350
ports/rps: Use aon_timer module.
ports/rp2: Remove rp2350 specific source.
ports/rp2: Use correct CMSIS header for rp2350.
ports/rp2: Add hardware_resets.
ports/rp2: For rp2350 just use aon timer
For rp2040 there's a workaround for RTC having only 1s resolution. This
    is not needed for rp2350
Stop setting PICO_RP2040_B* for rp2350
Only set PICO_RP2040_USB_DEVICE_ENUMERATION_FIX for rp2040

Changes:
- NUM_BANK0_GPIOS > pins defined in pins.csv = hardfault
- make-pins.py: NUM_GPIOS is hard-coded in make-pins.py, make it bigger
- machine_pin.h: Pin "ID" must be six bits, not five (breaks bit packing?)
- mphalport.h/machine_pin.c: open drain mask must be 64bits.

NUM_GPIOS amd NUM_EXT_GPIOS is currently hardcoded in this python
script.

Pass the count in via the new parameters num-gpios and num-ext-gpios.
These default to the current values supported by Pico 30/10. This can be
changed with PICO_NUM_GPIOS and PICO_NUM_EXT_GPIOS in
mpconfigboard.cmake. Without this you will get a build error because
NUM_BANK0_GPIOS can be too small.

Add PSRAM support with auto detection.

Performs a best-effort attempt to detect attached PSRAM,
configure it and *add* it to the MicroPython heap.

If PSRAM is not present, should fall back to use internal
RAM.

Introduce two new port/board defines:

* MICROPY_HW_ENABLE_PSRAM to enable PSRAM.
* MICROPY_HW_PSRAM_CS_PIN to define the chip-select pin.

Changes:

ports/rp2/rp2_psram.c/h: Add new PSRAM module.
ports/rp2/main.c: Add optional PSRAM support.
ports/rp2/CMakeLists.txt: Include rp2_psram.c.
ports/rp2/rp2_flash.c: Add buffered write to avoid reads from PSRAM.
ports/rp2/mpconfigport.h: Enable MICROPY_GC_SPLIT_HEAP
for boards that set MICROPY_HW_ENABLE_PSRAM.

My tests found issues when PSRAM is combined with the existing
RAM in a split-heap configuration. Since this option is not
enabled by default on RP2 I have changed it to be optional.

PSRAM will be used exclusively if MICROPY_GC_SPLIT_HEAP == 0,
it will be added to RAM if MICROPY_GC_SPLIT_HEAP == 1,
and the system will fall back to RAM only if it's not detected.
