all: Remove use of deprecated CONFIG_UART_x_NRF_HW_ASYNC

nordic-krch · rlubos · commit 684552a809df · 2026-02-10T17:36:45.000+01:00
Removing use of deprecated Kconfig option which enabled RX
byte counting using the TIMER peripheral. In all this cases, it is
not needed as low power UART will receive data reliably without
that option as well.
