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.

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.
