[PATCH] earlycon: Fix __earlycon_table stride... again

[Daniel Kurtz]

Commit 470ca0de69fe ("serial: earlycon: Enable earlycon without command
line param") added EARLYCON_TABLE().

Commit 99492c39f39f ("earlycon: Fix __earlycon_table stride") fixed
EARLYCON_TABLE() alignment to 32-bytes.

Commit 2eaa790989e0 ("earlycon: Use common framework for earlycon
declarations") added the compatible field, which bumped EARLYCON_TABLE()
alignment to 128 bytes (LCM of size of all fields of struct earlycon_id.

Correct the struct definition and linker alignment to match.
