[PATCH 2/3] Documentation: leds: MT6370: Properly wrap hw_pattern chart

[Bagas Sanjaya <bagasdotme@gmail.com>]

The pattern diagram (chart) of /sys/class/leds/<led>/hw_pattern is
wrapped in literal code block. However, the block indentation is
interrupted by Icurr axis label, hence below warnings:

Documentation/leds/leds-mt6370-rgb.rst:39: WARNING: Literal block ends without a blank line; unexpected unindent.
Documentation/leds/leds-mt6370-rgb.rst:41: WARNING: Line block ends without a blank line.
Documentation/leds/leds-mt6370-rgb.rst:46: WARNING: Unexpected indentation.
Documentation/leds/leds-mt6370-rgb.rst:44: WARNING: Inline substitution_reference start-string without end-string.

Fix the chart indentation by adding 4 more spaces so that the axis label
is in the code block.
