29f87c3a0f boards: esp32: add XIP support and enable bootloader build 
Disable RTC WDT enabled (by default) by 2nd stage bootloader in ESP-IDF.
This WDT timer ensures correct hand-over and startup sequence from
bootloader to application.

Enabling bootloader caused system clock initialization to fail
when clock rate is greater then 80MHz. This also fixes
esp32 clock source code.

e18fcbba5a device: Const-ify all device driver instance pointers 
Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.

A coccinelle rule is used for this:

@r_const_dev_1
  disable optional_qualifier
@
@@
-struct device *
+const struct device *

@r_const_dev_2
 disable optional_qualifier
@
@@
-struct device * const
+const struct device *

Fixes #27399

af6140cc0d device: Apply config_info rename everywhere 
Via coccinelle:

@r_device_config@
struct device *D;
@@

D->
-	config_info
+	config

And 2 grep/sed rules for macros:

git grep -rlz 'dev)->config_info' |
	xargs -0 sed -i 's/dev)->config_info/dev)->config/g'

git grep -rlz 'dev->config_info' |
	xargs -0 sed -i 's/dev->config_info/dev->config/g'

Fixes #27397

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
