Fix Planck and Preonic builds (#5658)

* Planck: Copy contents of Planck rules.mk to each revision * Planck: Delete Planck rules.mk * Planck: Concatenate duplicate rules Concatenate rules that are set and then overridden into one setting. * Preonic: Copy contents of Preonic rules.mk to each revision * Preonic: Delete Preonic rules.mk * Preonic: Concatenate duplicate rules Concatenate rules that are set and then overridden into one setting. * Planck: Delete non-specific Bootloader settings from revs. 1 and 2 Deleted BOOTLOADER setting code block, as the checks were only valid for revs. 3-5 and the Planck Light. Neither Planck rev1 or rev2 set the bootloader via rules.mk, so there's no setting of BOOTLOADER in their rules.mk files. * Preonic: Fix BOOTLOADER settings code blocks * Preonic: delete extra blank lines from rules.mk files * Preonic: delete AVR-type hardware config blocks from rev3 * Update Planck and Preonic readme files - update Hardware Supported - update/add Install Examples - update Docs paragraph * Enable Bootmagic Lite where it is disabled Enabled Bootmagic Lite for: - Planck Light - Planck revs. 1-5 - Preonic revs. 1 and 2 * Remove `planck_grid` from LAYOUTS rule for all Planck revisions Community has landed on `ortho_4x12`, which is already set; `planck_grid` is redundant.
