Tiago Medicci Serrano e38b4b2103 espressif: fix linker to include the reserved area of RTC memory
Basically, it reserves an area of the RTC memory to preserve the
RTC timer.

Please refer to:
fa76c82a5b

This commit also removes the rtc.dummy section because C3, C6 and
H2 don't need to skip it once the region is accessed by the same
address space using the instruction and data bus.
