_acquire() is not required in constructor, since we are not performing
any operation on SPI bus yet. Just initialize the pins/hw
Destructor is required to clear _owner else SPI format/frequency will not be
set if object is recreated. We do not free SPI bus, but init again in hardware
may or may not change frequency/format.
```
{
SPI spi1(...);
spi1.transfer(...);
}
{
SPI spi1(...);
spi1.transfer(...);
}
```
