SPIFBlockDevice was using SingletonPtr without an include,
and only getting it via SPI.h.
Spotted while changing SPI to not use SingletonPtr - now
abandoned, but still this shouldn't have been relying on it.
This commit takes some of the work done on the SPI class from #8445, and
refines it, to provide the per-peripheral mutex functionality.
This also implements GPIO-based SSEL, which exposes a new
select()/deselect() API for users to group transfers, and should work on
every platform (unlike the HAL-based SSEL). This requires users to use a
new constructor to avoid backwards compatibility issues.
To activate the per-peripheral mutex, the HAL must define SPI_COUNT and
provide spi_get_peripheral_name(). (In #8445 this is a reworked
spi_get_module, but the name is changed here to avoid a collision with
existing HALs - this commit is designed to work without wider HAL
changes).
Fixes: #9149

use linker scripts to add heap and stack - this is inconsistent
