[edk2-devel] [PATCH edk2-platforms] SbsaQemu: move code outside of methods in DSDT

["Marcin Juszkiewicz" <marcin.juszkiewicz@linaro.org>]

IASL complained that DSDT is not optimal:

Dsdt.iiii
83:             Name (RBUF, ResourceTemplate() {
Remark   2173 - Creation of named objects within a method is highly
inefficient, use globals or method local variables instead ^
(\_SB.USB0._CRS)

Dsdt.iiii
377:       Name (RBUF, ResourceTemplate () {
Remark   2173 - Creation of named objects within a method is highly
inefficient, use globals or method local variables instead ^
(\_SB.PCI0._CRS)
