esp32/machine_hw_spi: Fix SPI default pins reordering on ESP32-S2/S3.

The index of machine_hw_spi_obj and machine_hw_spi_default_pins arrays is
assigned to 0 for ARG_id==HSPI_HOST and 1 for another SPI.  On ESP32S2 and
S3 HSPI_HOST=2 so the first set (idx=0) of default pins is used for
SPI(id=2) aka HSPI/SPI3 and the second set (idx=1) for SPI(id=1) aka
FSPI/SPI2.  This makes a misleading mess in MICROPY_HW_SPIxxxx definitions
and it is also in contradiction to the comments around the definitions.

Change the test of ARG_id to fix the order of machine_hw_spi_default_pins.

This change might require adjusting MICROPY_HW_SPIxxxx definitions in
mpconfigboard.h of S2/S3 based boards.
