7cf99aa2f2 dts: use 'cdns,' instead of 'cadence,' consistently
The Linux vendor prefixes list uses 'cdns'. Match it, especially since
we have that prefix in our own list as well.

4303cfdb3c hal: esp32: driver changes to allow HAL update
hal_espressif repository was updated from esp-idf v4.2
to esp-idf v4.3 to allow latest Espressif chips integration.
As a consequence, it added a few changes in drivers
and peripherals. To maintain bisectability, changes in this
PR cannot be split. Here are some details:

wifi: update linker script by adding libphy and new attributes.

spi: update some APIs and fixed missing wait_idle check

4acac3e9ef drivers: esp32/clock_control: Add Clock Driver
- Support PLL for Higher Frequencies 80,160,240 MHz
- Support XTAL Frequencies 26MHz, 40MHz
- Clock Driver can't be disabled, because all of the other drivers
will depend on it to get their operating Frequency based on chosen
clock source (XTAL/PLL).

- Add needed references to BBPLL i2c bus ROM functions.
- Add `rtc` node to Device Tree.
- Since All Peripherals Frequency is depending on CPU_CLK Source,
`clock-source` property added to CPU node

43a7d26603 drivers: entropy: replace CONFIG_ENTROPY_NAME with DT macro
Replace CONFIG_ENTROPY_NAME with DT_CHOSEN_ZEPHYR_ENTROPY_LABEL.  We now
set zephyr,entropy in the chosen node of the device tree to the entropy
device.

This allows us to remove CONFIG_ENTROPY_NAME from dts_fixup.h.  Also
remove any other stale ENTROPY related defines in dts_fixup.h files.

2d035c4191 drivers: esp32: Add UART Driver with FIFO/Interrupt support
- Fixes #3981
- Implement UART Polling functions
- Implement UART Interrupt APIs
- Remove dependency on esp32_rom_uart_xxx functions
- Update Device tree with UART addresses and pin config
- Update ESP32 UART KConfig

Notes about implementation:
- Interrupts now defined as a local macros, and should be removed
later on, when interrupts for esp32 are supported in dts

- Threshold interrupts are used for TX/RX
- Reseting FIFOs using _RST bit will corrupt FIFO of UART2 when used for
UART1 and vice-versa, so a generic way is used for all three UARTs

- Old Silicon rev is not supported

7d56fc35fd dts: Add information about CPU frequency to the cpu nodes
This commit adds 'clock-frequency' property to the cpu nodes.
The clock frequency specified in the added property is used
during platform configuration. Examples:

- The SWO logger uses clock frequency to configure SWO output.
- Plenty of platforms need CPU clock specified for their HAL.
- Most of devices with USB needs information about CPU clock
  in order to configure USB clock source.
