Silabs siwx91x includes a memory controller for (Quad-)SPI PSRAM. It
allows the application to use the PSRAM as if it was any other RAM.

This driver allow to use Zephyr native IP stack or the IP stack provided
by HAL / WiseConnect.
The WiseConnect implementation may take advantage of the specific
features provided by the 917 (power consumption, speed,
validation...).
Some notable features are not available with this interface:
- It seems Zephyr does not provide API to offload multicast membership
management. User should be to directly call WiseConnect APIs
- Support for ICMP frames is difficult. Note that WiseConnect
automatically answer to ping request. It is just not possible to
send ping requests and receive ping responses.
- Zephyr and WiseConnect both support TLS offloading. However this
patch does not implement it.
- Reentrancy in the WiseConnect side is uncertain.
This implementation has been tested with samples/net/wifi/ (which relies
on subsys/net/lib/shell).

Driver was tested with a custom application which enabled the BT_SHELL.
Basic functionalities were verified:
- Scanning
- Advertising
- Connecting
Configuration needed for the test:
- CONFIG_BT=y
- CONFIG_BT_PERIPHERAL=y
- CONFIG_BT_CENTRAL=y
- CONFIG_BT_SHELL=y
- CONFIG_SHELL=y

Support for random number generator is required for most of the
cryptographic operations, including support for WiFi and TLS.
