zenfone8: Import and build bootctrl from CAF
Bootctrl: https://source.codeaurora.org/quic/la/platform/hardware/qcom/bootctrl/tree/?h=LA.UM.9.14.r1-16700-LAHAINA.0
recovery-ufs-bsg: https://source.codeaurora.org/quic/la/platform/vendor/qcom-opensource/recovery-ext/tag/?h=LA.UM.9.14.r1-16700-LAHAINA.0
Recovery:
* Removed all guard related to the ufs frameworks. Lahaina use it so ne need to add additional stuff for it (soong namespace)
-https://source.codeaurora.org/quic/la/platform/vendor/qcom/lahaina/commit/BoardConfig.mk?h=LA.UM.9.14.r1-16300-LAHAINA.0&id=ffb36a29fbac3a75130ea6e0cc159958bf55dab6
* Removed too, the guard related to GENERIC_KERNEL_HEADERS. Our kernel (5.4) doesn't support previous scsi ufs

- * First, the polynomial itself and its table of feedback terms. The
- * polynomial is
- * X^32+X^26+X^23+X^22+X^16+X^12+X^11+X^10+X^8+X^7+X^5+X^4+X^2+X^1+X^0
- *
- * Note that we take it "backwards" and put the highest-order term in
- * the lowest-order bit. The X^32 term is "implied"; the LSB is the
- * X^31 term, etc. The X^0 term (usually shown as "+1") results in
- * the MSB being 1
- *
- * Note that the usual hardware shift register implementation, which
- * is what we're using (we're merely optimizing it by doing eight-bit
- * chunks at a time) shifts bits into the lowest-order term. In our
- * implementation, that means shifting towards the right. Why do we
- * do it this way? Because the calculated CRC must be transmitted in
- * order from highest-order term to lowest-order term. UARTs transmit
- * characters in order from LSB to MSB. By storing the CRC this way
- * we hand it to the UART in the order low-byte to high-byte; the UART
- * sends each low-bit to hight-bit; and the result is transmission bit
- * by bit from highest- to lowest-order term without requiring any bit
- * shuffling on our part. Reception works similarly
- *
- * The feedback terms table consists of 256, 32-bit entries. Notes
- *
- * The table can be generated at runtime if desired; code to do so
- * is shown later. It might not be obvious, but the feedback
- * terms simply represent the results of eight shift/xor opera
- * tions for all combinations of data and CRC register values
- *
- * The values must be right-shifted by eight bits by the "updcrc
- * logic; the shift must be unsigned (bring in zeroes). On some
- * hardware you could probably optimize the shift in assembler by
- * using byte-swap instructions
- * polynomial $edb88320
