"The Promised Land" is a profound concept that has been a part of world literature and art for several thousand years. It is most certainly not uniquely associated with Bruce Springsteen.
Undoubtedly, the concept and the image of The Promised Land resonate with Springsteen because of his Roman Catholic faith. The concept of "The Promised Land" comes up again and again in the theology and teaching of all forms of Judaism and Christianity, throughout all history (and may well come up in Islam as well, although I do not know much about Islam).
The concept originates in the Jewish Bible, the Old Testament, the Book of Genesis, and in many other places after that, throughout the Jewish and Christian Bibles (the Old and New Testaments).
"The Promised Land" refers, geographically, to the land of Canaan, which is a part of modern-day Israel. A later name for Canaan or The Promised Land is "Zion".

In the Book of Genesis, God establishes an eternal contract with the family of a man named Abraham; he is the progenitor of the Hebrews, later knows as the Jews or the Israelites. God tells the Hebrew people that they are the Chosen People of God. He promises them that they will inherit the Promised Land (Canaan) and be able to live there as a nation. Once the entire race of the Hebrews have been freed from slavery in Egypt, the prophet Moses leads the Hebrews to the edge of the Promised Land, and the military leader Joshua takes the Hebrews into the Promised Land and conquers it. This leads eventually to the establishment of the city of Jerusalem, and the nations of Israel and Judah.
Throughout the subsequent history of the world, many writers, poets, and musicians have made frequent references to "The Promised Land". Not only was this a literal reference to the Bible stories; it also became a literary and artistic symbol for any ethnic group achieving freedom from oppression, and peace after struggle and suffering.
Within the last two hundred years, images of "The Promised Land" can be found frequently in African-American spirituals, black gospel, and most especially in reggae music and the Rastafarian religion. But it can be found throughout the entire history of any kind of Christian or Jewish sacred music or any music inspired by those traditions.
African-Americans who were slaves in the USA in the 18th and 19th centuries, and who became Christians, saw the Bible stories about the Hebrew slaves gaining their freedom and inheriting and possessing the Promised Land to be a metaphor for their own struggle to achieve emancipation and live as free citizens in the USA. That is why there are so many references to The Promised Land throughout African-American spirituals. African-American spirituals are the direct ancestors of the blues, jazz, gospel, and rock and roll music. And Bruce Springsteen's music, too.
The Promised Land is a very important and frequently-referenced concept of the USA's African-American civil rights movement for desegregation. The Reverend Dr. Martin Luther King, like all other Christian pastors, made frequent references to The Promised Land in his sermons and speeches.
For the Jamaicans and other adherents of the Rastafarian religion, The Promised Land refered to their own struggle for equality and freedom for their ethnic group, but also had specific references to nations in Africa gaining independence from European colonial influences in the 20th-century. You can find many references to "Zion" and "The Promised Land" in reggae music, as a result of this.
No, "The Promised Land" has nothing to do with Bruce Springsteen, per se. It has to do with thousands of years of world culture.
