[PATCH 2/2] clang-format: align consecutive macros

[Michael Riesch]

clang-format 9 introduced the option "AlignConsecutiveMacros".
Set it to "AcrossEmptyLinesAndComments" in order to avoid macro
definitions of the form:

    #define MAGIC_REGISTER_1 0x42
    #define MAGIC_REGISTER_BIT_FLIP BIT(2)
    /* important comment */
    #define MAGIC_REGISTER_BIT_ENABLE BIT(12)

    #define MAGIC_REGISTER_2 0x43

With the option set to "AcrossEmptyLinesAndComments", they will
be converted to

    #define MAGIC_REGISTER_1	      0x42
    #define MAGIC_REGISTER_BIT_FLIP   BIT(2)
    /* important comment */
    #define MAGIC_REGISTER_BIT_ENABLE BIT(12)

    #define MAGIC_REGISTER_2	      0x43

which seems to be the convention in the kernel code base.
