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));
| ^
../drivers/rtc/rtc-renesas-rtca3.c:369:23: error: call to undeclared function 'FIELD_GET'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
369 | tm->tm_sec = bcd2bin(FIELD_GET(RTCA3_RSECAR_SEC, sec));
| ^
../drivers/rtc/rtc-renesas-rtca3.c:476:11: error: call to undeclared function 'FIELD_GET'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
476 | cycles = FIELD_GET(RTCA3_RADJ_ADJ, radj);

../drivers/rtc/rtc-renesas-rtca3.c:658:8: error: call to undeclared function 'FIELD_PREP'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
658 | val = FIELD_PREP(RTCA3_RCR1_PES, RTCA3_RCR1_PES_1_64_SEC);
