e5b280f173 dport: Bigfix dport_read code move to IRAM
A new method of workaround an error with DPORT is to ensure that the APB is read and followed by the DPORT register without interruptions and pauses. This fix places this implementation in the IRAM to exclude errors associated with the cache miss.

8f80cc733d soc: Change DPORT access
When two CPUs read the area of the DPORT and the area of the APB, the result is corrupted for the CPU that read the APB area.
And another CPU has valid data.

The method of eliminating this error.
Before reading the registers of the DPORT, make a preliminary reading of the APB register.
In this case, the joint access of the two CPUs to the registers of the APB and the DPORT is successful.

a72b1abc51 esp32: disable DPORT access protection when doing esp_restart
DPORT access protection can not work when the other CPU is stalled.
Writes to DPORT registers in esp_restart caused the program to hang due
to access protection, and the reset happened due to RTC_WDT, not SW_RST.
This change adds esp_dport_access_int_deinit function and calls it from
esp_restart once the other core is stalled.

f7e8856520 component/esp32 : fix dualcore bug
1. When dual core cpu run access DPORT register, must do protection.
2. If access DPORT register, must use DPORT_REG_READ/DPORT_REG_WRITE and DPORT_XXX register operation macro.
