Document update needed about patch

[kimjj81]

Dear.

Apply mbedTLS patches into deps/mbedtls using:

patch -p1 < ../../patches/mbedtls_ocf_patch_1

patch -p1 < ../../patches/mbedtls_iotivity_constrained_patch_2

But there are
01_mbedtls_dynamic-content-length_p1.patch
02_mbedtls_dynamic-content-length_p2.patch
03_mbedtls_dynamic-content-length_p3.patch
04_mbedtls_dynamic-content-length_p4.patch
05_mbedtls_ocf-samsung.patch
06_mbedtls_ocf-microsoft.patch
07_mbedtls_constrained.patch

What are different between those?

What should I patch?
I use rasberry pi, linux on x86 (for research, study) and zephyr (for product)

Thanks.
