doc: intel: Update serial driver changes in slimbootloader.rst
Now, Slim Bootloader uses NS16550_DYNAMIC to support serial port
configuration at runtime, so no more code change is required.
Therefore, remove unnecessary steps and fix minor typo.

Build Instruction for Slim Bootloader for LeafHill (APL) target
---------------------------------------------------------------
-LeafHill is using PCI UART2 device as a serial port.
-For MEM32 serial port, CONFIG_SYS_NS16550_MEM32 needs to be enabled in U-Boot.
+Prepare U-Boot and Slim Bootloader as described at the beginning of this page.
+Also, the PayloadId needs to be set for APL board.
-1. Enable CONFIG_SYS_NS16550_MEM32 in U-Boot::

-3. Copy u-boot-dtb.bin to Slim Bootloader.
- Slim Bootloader looks for a payload from the specific location.
- Copy the build u-boot-dtb.bin to the expected location::
-
- $ mkdir -p <Slim Bootloader Dir>/PayloadPkg/PayloadBins/
