This replaces 'SPDX-License-Identifier' tags in all the files under
soc/mediatek/mt8195 for better code re-use in other open source
software stack.
These files were originally from MediaTek and follow coreboot's main
license: "GPL-2.0-only". Now MediaTek replaces these files to
"GPL-2.0-only OR MIT" license.

Move mtk_i2c_max_step_cnt, mtk_i2c_check_ac_timing, mtk_i2c_speed_init
and mtk_i2c_calculate_speed to common folder to share with MT8186.

ltiming and clock_div are not support for MT8173, so we separate them
to weak function: mtk_i2c_dump_more_info()

1. The original algorithm for I2C speed cannot always make the
timing meet I2C specification so a new algorithm is introduced
to calculate the timing parameters more correctly.
2. Some I2C buses should be initialized in a different speed while
the original implementation was fixed at fast mode (400Khz).
So the mtk_i2c_bus_init is now also taking an extra speed
parameter.
There is an equivalent change in kernel side:
