ESP32C3: DR_REG_I2S_BASE should be DR_REG_I2S0_BASE? (IDFGH-11518)

Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

General issue report

In soc/esp32c3/include/soc/soc.h:23

#define REG_I2S_BASE(i)                         (DR_REG_I2S_BASE + (i) * 0x1E000)

but I'm getting compile errors, because DR_REG_I2S_BASE isn't defined anywhere for the C3, unlike 32/S2/S3/C6. What does exist in soc/esp32c3/include/soc/reg_base.h:44:

#define DR_REG_I2S0_BASE                        0x6002D000

If I replace DR_REG_I2S_BASE with DR_REG_I2S0_BASE in soc.h, it compiles fine. Is this an oversight, or am I missing something here?
