Add initial support for the I2S peripheral on ESP32.
Add I2S character driver and generic I2S audio driver.
Include i2schar defconfig for ESP32-DevKitC board.
When compiling my project, the time to generate allsyms decreased from tens of seconds to 2 seconds

Fixes minor issue with a trace (build failure with -Werror):
libelf/libelf_symbols.c:310:41: error: pointer of type 'void *' used in arithmetic [-Werror=pointer-arith]
310 | (uintptr_t)(sym->st_value + symbol->sym_value));
In SMP mode, if all cores start at same time, all from __start(),
then only primary need do initialize, so others core should wait
primary, use 'sev' let the non-primary continue to __cpuN_start().

NON-primary cpu will invalidate cpu0's cache L2, that will caused cpu0's data mismatch, and then system crash

The IDMA needs to have 32 bit word alignment, in fact it will
AND off the lower 2 bits of the value stored in IDMABASE0R.
This bug was masked by CONFIG_ARMV7M_DCACHE causing proper word alignment
and also FAT_DMAMEMORY being aligned.
This commit extends the unaligned logic (used for dcache) to take into account
the need for a buffer copy when the buffer is ot 32 bit word.
It leverages the fact that when CONFIG_ARMV7M_DCACHE is not defined the up_xxxxx_dcache are nops.
1. Don't handle invalid or empty pte entries
num_partition_entries field in GPT typically means number of maximum entries
and not the number of used entries. Empty entries are indentified with
"0" partition type guid. Loop through all the entries
2. Fix the GPT partition size calculation
"ending_lba" is included in the partition, it is not the start of the next one.
Thus the correct size of the partition is end-start+1
