Daniel Golle d3a337a592 uboot-mediatek: additions from MTK SDK
* updated SNAND/SNFI driver brings support for MT7981
 * add support for MediaTek NAND Memory bad Block Management (NMBM)
   (not used for any boards atm, but could be useful in future)
 * wire up NMBM support for MT7622, MT7629, MT7981 and MT7986
 * replace some local patches with updated version from SDK
 * bring some legacy precompiler symbols which haven't been converted
   into Kconfig symbols in U-Boot 2022.07, remove when bumbping to
   U-Boot 2022.10:
   100-28-include-configs-mt7986-h-from-SDK.patch

Subject: [PATCH 32/71] clk: remove log_ret from clk_get_rate
The return value of clk_get_rate is ulong, an unsigned type. The size of
ulong depends on the cpu architecture, i.e. 4 bytes on 32-bit CPUs and
8 bytes on 64-bit CPUs.
However log_ret only accepts and returns value in int type, a fixed 4-byte
type. This may truncate the real clock value and cause unexpected error on
64-bit platforms.
This patch removes log_ret to solve this issue.
