868da0741c aes/sha/mpi: Bugfix a use of shared registers.
This commit resolves a blocking in esp_aes_block function.

Introduce:
The problem was in the fact that AES is switched off at the moment when he should give out the processed data. But because of the disabled, the operation can not be completed successfully, there is an infinite hang. The reason for this behavior is that the registers for controlling the inclusion of AES, SHA, MPI have shared registers and they were not protected from sharing.

Fix some related issue with shared using of AES SHA RSA accelerators.

Closes: https://github.com/espressif/esp-idf/issues/2295#issuecomment-432898137

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.

26a3cb93c7 component/soc : move dport access header files to soc
1. move dport access header files to soc
2. reduce dport register write protection. Only protect read operation

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.

0647d1e922 esp32 hwcrypto: Rework hardware crypto locking
Should protect against concurrent use of hardware crypto primitives,
with good performance.

Not necessary to call esp_aes_acquire_hardware(),
esp_sha_acquire_hardware(), etc when using these APIs. These are
provided for external users calling the hardware crypto hardware
directly, to coexist with this implementation.
