sn32f2: inherit clocks from chibios (#203)

* Revert "TEMP: HACK: define clock for sn32. 48Mhz"

This reverts commit db1a0f9910e83b1c1dc4c135038e5d998a5cab08.

* inherit clocks from chibios
needs https://github.com/SonixQMK/ChibiOS-Contrib/pull/38

* sn32f2xx: use tickless mode

* pull up chibi

* satisfy linter

* Pull up Chibios-Contrib

* more chibios-contrib

* even more chibi

* sn32f2: bump timedelta to 4

* frequency updates

* hi, please boot

* Revert "hi, please boot"

This reverts commit 97cc1f94cc684873cdf90d0c1a8df43ac023e526.

* Revert "sn32f2: bump timedelta to 4"

This reverts commit ad7c0f9e5a5e9774ac42575e17761fe116653308.

* testing: rgb effects

* pull up chibios-contrib

* matrix: here have some LSD

* k556: here be drugs

* a pinch of coke will do it

* testing: shorter period

* Revert "testing: shorter period"

This reverts commit 4dd9aa8f8fdfed3290feda0215514d989847ea71.

* remove the multipliers

* matrix: revert to original state

* rgb matrix: calculate the ticks from the frequency

* remove redundant include

* Ms

* add correction value

* it's S

* use some hardcoded for now

* bump the period

* scale it down

* scale it down more

* testing: 20khz

* testing: 2kz

* shoot for 20khz, THEN calculate the period

* flip it

* match it

* make sure the value is uint32

* testing: break the time machine

* Revert "testing: break the time machine"

This reverts commit 2f9a66adb055adc80d90930d2bafc18b0abcadb8.

* ms

* Pull up chibios-contrib

* testing: back to hw systick

* testing: back to s

* testing: back to 16bit

* testing: tickless

* testing: timedelta 4

* chibi updates + back to 2

* more chibios

* latest chibios commit

* match the registers

* testing: frequency

* testing: more freq

* testing: use ILRC for systick

* testing: hack

* testing: more ihrc

* testing: more freq

* testing: freq 2

* testing: freq 4

* test: harcode it

* testing: timedelta

* remove this for now

* Revert "testing: timedelta"

This reverts commit a6722c841e4f26b4d34d06b7303d21d2668e0459.

* update configs

* Revert "remove this for now"

This reverts commit f344030ea531710b3988f8137c4ce42676fbd864.

* workaround the chibios timer bug

chThdSleep() fails when the interval does not just fit into the system timer
this is noticeable with a resolution of 16bits in high ST frequencies

* shared matrix: revert to original target frequency

* Revert "workaround the chibios timer bug"

This reverts commit 33affe54c93fffe8cb18039a2183681a6b2644e1.

* Revert "testing: rgb effects"

This reverts commit c112770a284203ed3cccee7fb14b89f2e8f0fd4b.

* Revert "k556: here be drugs"

This reverts commit b9b5aad64cf19daa40541fbd745322bba73ab9df.
