This change moves all PDL drivers into common source and include
directories to alleviate issue with Windows version of GNU Make 4.x
maximum command line length limit.
1. Removed random i/o glitches occurring during device reconfiguration
2. Fixed hazardous reads occurring at the end of transfer resulting
in incorrect values being received
3. Added spi_free() function
4. Replaced default M0 image with a one ignoring i/o reservation. This is
a workaround for missing proper destructors in Mbed drivers and BlockDevice
tests failing on repeated initialization
Fixes issue #9620.
The targets/TARGET_Cypress/TARGET_PSOC6 is dedicated to the mbed-os HAL
and PSoC 6 MCU targets developed by Cypress Semiconductor. Move the
existing port developed by Future Electronics to TARGET_PSOC_FUTURE
and update the labels in targets.json appropriately.
