- 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 Signed-off-by: Mohamed ElShahawi <ExtremeGTX@hotmail.com>
