6a2f7b6f88 ld: rename .ext_ram.noinit to .ext_ram_noinit
Older versions of the coredump utility tool do not correctly
handle this nameing scheme. Rename to keep forward compatibility.

b85011c15f esp32: Add support for noinit variables in SPIRAM
Add Kconfig option SPIRAM_ALLOW_NOINIT_EXTERNAL_MEMORY
When enabled, a new linker script rule (from esp32.extram.noinit.ld)
places any variables in the .ext_ram.noinit section in SPIRAM.

This section is exempted from the startup SPIRAM memory test and is
not zero-initialized or added to the malloc pool, making it usable
for noinit variables that persist across reset.

The EXT_RAM_NOINIT_ATTR macro places variables in this section.
