soc esp32: Removes parentheses from RTC_MEM_xyz macros that expand directly to single numbers

Not necessary in these cases, and prevents parens from expanding into the
assembly code such as added in 562ab01046f05ad12af40eb8015311486cd8cc91  -
a pattern which is accepted by GCC assembler but illegal syntax for LLVM assembler.

As reported https://github.com/espressif/llvm-project/issues/35#issuecomment-726853574
