PM / sleep: declare __tracedata symbols as char[] rather than char
Accessing more than one byte from a symbol declared simply 'char' is undefined
behavior, as reported by UBSAN:
UBSAN: Undefined behaviour in drivers/base/power/trace.c:178:18
load of address ffffffff8203fc78 with insufficient space
for an object of type 'char'
Avoid this by declaring the symbols as arrays.
