a6e14c37b2 SPI: chip select can now be kept active if the bus has been acquired
The user can now request the chip select to remain active after the current
transfer. In order to do so, he MUST acquire the bus first with `spi_device_acquire_bus()`
function, else, an error is returned.

0c3653b1fd spi_master: fix master HD mode cannot correctly receive data issue when using DMA.
Issue Description:
If master is in HD mode, if it sends data without receiving data, it will
still enable the RX DMA because of old version ESP32 silicon issue. And
because there is no correctly linked RX DMA descriptor, an
``inlink_dscr_error`` intr will be seen, which will influence the
following RX transactions.

Solution:
Trigge this workaround only in FD mode.

TODO:
Add a test to check if this workaround related issue does exit. If so,
reporting to Digital Team is also needed.

1966f00f0b soc: updates caps usage
We should define caps as 1 if true. When use the caps macros, #if and
 #if ! should be used instead of #ifdef/#ifndef.

27a6f2666a spi_master: refactor hal context structures
This commit seperates the hal context into different configuration
structures based on their members' definitions. Through refactoring
spi_master.c, the device related configuration should be passed in and
set each time before a new transaction. The transaction related
configuration now is a local variable in case of the fact that error
occurs without any notice when user forgets to pass new transaction
configuration in (which means the old driver will use the trans_config
that is saved from last transaction).

Besides, via above refactor, this commit fixs a bug which leads to
wrong cs polarity setting.
Closes https://github.com/espressif/esp-idf/pull/5490

Moreover, via above refactor, this commit also fixs a bug about duplex
mode switching when multiple devices are added to the bus.
