yinshengkai 8c035a2414 drivers/serial/xlnxps: add polling mode support for serial drivers 
Adds CONFIG_UART_XLNXPS_POLLING options to enable polling mode for
transmission. This avoids TX interrupts and reduces interrupt latency
at the cost of blocking during TX.

Implements sendbuf() method for efficient buffer transmission
in polling mode.
