Subject: [PATCH v6 4/9] rtc: renesas-rtca3: Fix compilation error on RISC-V

From: Claudiu Beznea <claudiu.beznea.uj@...renesas.com>

Fix the following compilation errors when building the RTCA3 for RISCV:

../drivers/rtc/rtc-renesas-rtca3.c:270:23: error: call to undeclared function 'FIELD_GET'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
  270 |         tm->tm_sec = bcd2bin(FIELD_GET(RTCA3_RSECCNT_SEC, sec));
      |                              ^
